Solid state Definition and 278 Threads

Is doping only to form an electric field in depletion region? Somehow I'm confused as far as I'm reading right now, the doping-generated carrier never discussed its role in the solar cell (other than leaving the ion and causing an electric field). Is not the number of carriers generated by...

I need a book that explains the physics of pn-junction diodes. Really any reference that can help me characterize or model a diode slightly better than the ideal case.

My university lecturer is very new, his lectures and notes are hard to follow and understand. He was a replacement to the old solid state physics lecturer and has designed the module from scratch, so it is unpolished in its current form. Can you please suggest some alternative resources...

Hello! I am going to enroll in a Solid State physics course and I want to know what good books are out there on the subject at an undergrad level. Any suggestions are appreciated! Thanks!

I wasn't sure if I should post this in general discussion or in solid state section, but am I the only one who finds the Kittel textbook horrible? It seems full of semi-empirical, basic math, and boring, surface level observations written as dryly as possible. I really like solid state physics...

I have found a couple other threads like this but I am looking for something at a very beginning level. I joined an experimental condensed matter group for the summer at the school where I will be matriculating as a first-year graduate student in the fall. They study various...

Homework Statement [/B] My question is more about the math of the problem. For equation 22.97, how do I construct a 3x3 matrix from a 12 element series? After constructing the matrix should I set the determinant equal to 0 where I will find the determinant has 3 solutions (2 being...

Hello I wish if anybody can enlighten me about experimental solid state physics. What they do every day? I mean who enroll in this major what careers they can find after completing their master degree in it? Is their a ph.D related to this major?

1) My teacher said that to analyze the properties of entire crystalline solid, we just need to analyze the properties of a unit cell, which is the smallest repeating unit of a crystalline solid. 2) But crystalline solids are known to be anisotropic, i.e. they have different properties in...

I am studying some solid state physics, in particular magnetism; I have a few questions about the explanations. My understanding is that paramagnetism is primarily an effect of the electron's spin-angular momentum: an unpaired electron will have a dipole moment which preferentially aligns with...

Hello I am having a really bad semester with solid state physics material, the book "introduction to solid state physics" by kittel is hard to follow and vague also it doesn't provide good explanations, always brief and fast. More than that my prof. is really good but have problems in...

Can you give the name of an excited book of solid state / condensed matter physics ( beside kittel and ashcroft ) ? a book than contains more talking about experimental rather than theory

What are the physics requeriments? and which book should i choose to begin to study?

I found Kittel very complicated and Ashcroft outdated. I want something rather new, written in a advanced but familiar manner.

I have begun studying Ashcroft + Mermin on my own, and am trying to follow the math in the text. They suggest that an electron in a metal with some momentum p(t) and exposed to a force f(t) will at some time later (t+dt) have a contribution to the momentum on the order of f(t)dt plus another...

Homework Statement *This is not my whole problem, I am only stuck on how to interpret one part of the question. Put simply, I want to find the expression for the density of energy levels in a given energy band per unit volume (in some crystal structure). Say I have an infinitesimal interval of...

I have to take a graduate level statistical mech course and a solid state physics course next sem (starting in feb).As I will be dealing with these topics for the first time, I'd like to like to prepare myself for them by learning/revising the math involved in them. What are the mathematical...

Hi everyone, I was hoping you guys could recommend some good solid-state physics textbooks or lecture notes. Thanks in advance.

As far as i understand, this is the principle of solid state x-ray detectors: 1. A photon of energy E enters the detector and goes through photoelectric absorption 2. As a result a photoelectron with energy (E - Φ) is ejected, where Φ is the binding energy required to eject the photoelectron...

I almost "get" it, but not quite. Can someone help? Here is my current understanding. Say you solve the Kronig-Penny model. You find that you get bands of N closely spaced energy levels, with large gaps between them. Under normal conditions, electrons fill the band to some level (let's say we...

I was wondering , are there any materials , metal or others, that have ions as the charge carriers that form current instead of electrons as in most metals.? and are the ohmic resistance in room temperature for example similar to materials were current is formed by electrons or is the resistance...

Hi everyone, I am a fourth year undergrad in physics. I am strongly considering graduate study in materials science, and I am wondering which course might have more impact both on my future studies and on admissions. The materials course seems like a broad overview of the subject, going over...

I am trying to undersand Ashcroft's derivation of energy density on page 38. I am following most of the arguments save EQ 2.30. Where did the vector go? I did follow my professors argument for converting to polar/spherical when the argument of a function is a modulus of a vector — exploiting...

What is the best book in solid state physics that contains problems and solutions?

Hello I've been wondering how certain solid state lasers could have a continuous lasing action (Nd YAG laser for instance ) If so,the understanding that the best lasing conditions are when the temperature Is lowest gets disproved(considering that a commendable quantity of heat is produced during...

hello every one , I want to know how we get phonon frequency spectrum theoretically by using three modes and dispersion relation, can anyone explain it. for example it is phonon energy correspond to density of state how it is obtain?

I have been pondering in my mind that if mathematically a partial is made up of an uncountable infinity of space, then how do particles not dismantle and keep a solid a "solid"? This might be a confusing question so, sorry.

I am into photonics research, and have been searching about this topic in vain, but almost nothing from Google shows up. So i turned here for some light. Do you guys know any material that changes its transparency when a laser (or light) illuminates from its side?

[Moderator's Note: Changed level of thread to "Advanced" based on the topics being asked about, all are graduate level topics.] I feel that I have an inadequate understanding of many important concepts in condensed matter physics, so I want to try to learn at least the most basic parts. So what...

In solid state physics, I learned that the velocity of a bloch electron is ##\frac{\partial E(k)}{\partial k}##, where ##E(k)## is the energy dispersion. This formula is derived on the basis of the assumption that electrons is a wave packet of bloch state in solids. However, I have a question...

It seems like when an electron moves to a higher energy level, even within the same band (conduction), the empty state should be a hole. But, we are told that in metals, electrons are the charge carriers. Do I just misunderstand what holes are? Or what is going on here?

In nuclear physics we have talked about the liquid drop model and the fermi gas model. My question is can a Fermi liquid and a Fermi gas be directly described using these models? Are they the same thing? i.e. If I wanted to decribe the difference between a fermi gas and a fermi liquid could I...
