Answer 1

Answer #1

a) The probability is given by

$f(Ec) Ec-E$

E_C -E_F =0.2 eV

k (Boltzmann Constant) = 8.617*10^-5 eVK^-1

0.468 8,617 10-5298

b)The probability that a particular energy level is empty is given by

$1 + expl_T$

E_V -E_F =-0.9 eV

k (Boltzmann Constant) = 8.617*10^-5 eVK^-1

ー0.9 1-f(EJ = 1 exp8.617 x10-5 29S 8,617 10-5298

Therefore

$i-f(E,,) = 6 * 10-10$

. Assume that the Fermi-level is 0.13 eV below the conduction band edge, EC. Assume Si (Eg = 1.1 eV) and T = 300 K. Calculate the probability that an electron will occupy a state at EC. Calculate the probability that an electron will occupy a state at EV. Also, calculate the probability that a state at EV will be free of electrons. In this particular case, will the sample be n-type or p-type? Assume that kT=0.025eV at 300K.

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...
