a system has two non-degenerate energy levels. energy gap is 0.1eV. calculate the probability that the system is in the higher energy level, when it is in thermal equilibrium with a heat reservoir of absolute temperature

i- 300K

ii-600K

iii-1000K

iv- 10000K

at what temperature is the probability equal to (v) 0.25 (vi) 0.4 (vii) 0.49

A system consists of N weakly interacting subsystems. Each subsystem possesses only two energy levels E1 and E2 each of them non-degenerate. (i) Draw rough sketches (i.e. from common sense, not from exact mathematics) of the temperature dependence of the mean energy and of the heat capacity of the system. (ii) Obtain an exact expression for the heat capacity of the system.

Consider a system of 2 particles and 4 non-degenerate energy levels with energies 0, E0, 2E0, 3E0, and 4E0. Taking into account the various ways the particles can fill those energy states, draw schemes of all the possible configurations with total energy E = 4E0 for the following cases: (a) The two particles are distinguishable. (b) The two particles are indistinguishable bosons. (c) The two particles are indistinguishable fermions.

A system consists of N = 106 particles that can occupy two energy levels: a nondegenerate ground state and a three-fold degenerate excited state, which is at an energy of 0.25 eV above the ground state. At a temperature of 960 K, find the number of particles in the ground state and in the excited state.

Silicon at 293 K has an energy gap Eg = 1.20 eV. (a) Calculate the probability that an electron state is occupied at the bottom of the conduction band at a temperature of 293 K, i.e., at an energy 1.20 eV above the top of the valence band. (b) Doping silicon with aluminum adds acceptor levels in the gap, 0.067 eV above the top of the valence band of pure silicon, and changes the effective Fermi energy. See Fig. 41-...
