Hi everyone, I have a problem about semiconductor.
I attempted once, but failed.
So please help me with it, thank you.
The area of the simple cubic crystal of the (100) plane within the unit cell is :
For the (100) plane, there are 4 atoms at the 4 corners of the square and one atom in the middle.
One fourth of each corner atom is enclosed within the unit cell, and middle atom is entirely within the unit cell, so the number of atoms on the (100) plane within the unit cell is
Therefore,
Atomic density on the (100) plane =
The answer has issue with the number of zeroes.
Yours is coming 14. However it is 18.

Hi everyone, I have a problem about multistage amplifier.
Please help me out, Thank you.
Consider the following multistage amplifier circuit. Given, B VA = 0, VcCE(Sat) = 0.2V and IVBE(ON) 0.7V for all transistors except Q3. VBE for Q3 is 0.655V. Determine the output voltage R6 1.8kΩ R1 9.77ko R2 24k0 R3 4kn R4 10ko R5 10ko 15 V Q8 Q10 Q5 Q6 output Q3 Q2 Q1 R9 15.7k R7 10kn R8 900 15 V
EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...

Can you please help me with this question. Much appreciated. So
I have a sample code, but we need to change the code in a way that
fits the problem.
A planar slab of material is initially at a temperature of 300 K. At the time t=0, microwave radiation is directed at the material, leading to internal heat generation that is uniform within the material. The sides of the slab experience negligible heat losses and a water bath maintains the...
