Hi,
please I need help with finding the minimal paths and cuts of the attached figure.
Here for the cuts I found: {1,6}, {7,3}, {6,4,2}, {2,5,7}
for the paths I get: {6,7},{1,2,3},{1,2,5,7},{1,4,7}
Do i miss some paths or cut please?
Also i cannot find the an expression for the...

Silicon is doped with 10^16 phosphorus atoms/cm^3.
At what temperature would the hole concentration be equal to 10% of the ionized impurity concentration?
2. Homework Equations
I am very confused with the equation I have .
The translation of the question is I...
Hard sphere is the "normal" cross section we have in classical physics namely pi*radius^2.
we are in quantum system and usually thr cross section is function of the particle speeds.
I am trying to understand this 3 body cross section with the quantum energy bound states but all those curves...
Hi everybody,
I was reading an article and I have this affirmation i don't know if correct:
the hard sphere collision cross section for 3 bodies always equal to zero. Is it true?
Why should it be?
Thank you
I think I get the notation. The main issue is what values for example the multiplicity can take? The maximum number of valence electrons is 8 i believe. and each electron can spin up or down. do i need to enumerate all combinations electron spin! this is a lot and I am not sure this the the...
Homework Statement
Give the full designation (e.g. 3P0) for all possible singlet, doublet, triplet and quartet S, P and D atomic states.
The Attempt at a Solution
I don't understand this question at all!
Up to which values does the angular momentum (supscript) and multiplicity...
100 N/C
thank i forgot all those units!
to find the final speed, i use the formula (Vfinal)^2-(Vinitial)^2=2a*(0.1 e-2)
when i did I found Vfinal =1.03 e6 m/s
the velocity difference i think is very small , it seems not right. did i do the question corretly?
thank you
Homework Statement
Calculate the velocity of an electron with 3 eV energy. This electron is accelerated by a constant field of 10 V/cm (parallel to the electron velocity) for 0.1 cm. What is the new electron velocity?
My other problem is the unit for the electric field . it bothers me...
Hi,
Please I would like to have some hints on this problem (from plasma processing course):
a) Starting from Eq. (2.4.7) of the textbook, derive an equation for the Maxwell-Boltzmann distribution in terms of electron energy.
b) Calculate the rate of ionization of molecular chlorine as a...
HI,
I have some questions on localized discharge in reactive ion etching. I just start studying etching ... it is a bit confusing.
Please can someone explain me this sentence?
"bromine containing plasmas have the tendency to form localized discharges. Localized discharges are particularly...
Hi,
Please can anyone give me some ideas of a "relatively" easy circuits involving digital and bipolar technology (meaning both technologies combined) to make a vlsi layout?
It is for a project and I really did not find something interesting.
Thank you
Homework Statement
compute the polarization state for the following scenarios:
The input light is randomly propagated in the z direction (figure attached) and then passes through a linear polarizer oriented 45° from either the x or y axis.
1-After the linear polarizer, the light passes...
Thank you
As you said the lens just allow the fringes to be seen at a focal length . For example if the distance to the screen was 2* focal length the fringes would appear blurry.
Homework Statement
The Young's double slit experiment is modified, as shown below, by placing a thin parallel glass plate of thickness d and refractive index n over one of the slits. Here a is the slit width in the x direction and b is the slit separation also in the x direction. The system...
