Hi dear friends
Please reffer to my work , I did part ( a )
Can someone help me to solve part( b )
Please

Right. The answer for (b) is the same as the answer for (a).falcon555 said:If we assume the number of electrons and the holes are the same ,then we suppose to get the same value

I don't think anyone would say that! (Look at that statement more carefully! )Or you mean to say
1 - 3.99 × 10^(-10) = 2.99 × 10^(-10)
That's what I always suspected, but I decided to make sure by going with the formulas. I wasn't sure if an electron at the very bottom of the conduction band implied a hole at the very top of the valence band until I worked the formulas.falcon555 said:Ok
It means without any extra calculation we can asume that both the values are the same as a rule of thumb, right?
Because the holes and the electrons are generated in pairs, right?
You're very welcome. Educational for me too!falcon555 said:Thank you very much bro for helping me.
You are great.
Cheers
Fermi-Dirac probability is a mathematical concept used in quantum mechanics to describe the probability of finding a fermion (particles with half-integer spin) in a particular energy state. It takes into account the exclusion principle, which states that no two identical fermions can occupy the same quantum state simultaneously.
Fermi-Dirac probability is unique in that it follows the Pauli exclusion principle, which affects the probability of finding fermions in a particular energy state. Other types of probability, such as classical or quantum probability, do not take into account this principle.
The formula for Fermi-Dirac probability is P(E) = 1 / (e^(E-EF) / kT + 1), where P(E) is the probability of finding a fermion in a particular energy state E, EF is the Fermi energy, k is the Boltzmann constant, and T is the temperature.
The Fermi energy (EF) is the highest occupied energy state in a system of fermions at absolute zero temperature. It serves as a reference point for calculating the probability of finding fermions in other energy states.
Fermi-Dirac probability is used in many areas of physics, including condensed matter physics, statistical mechanics, and quantum field theory. It is also used in the study of electronic devices, such as transistors and semiconductors, and in understanding the behavior of particles in the early universe.
