hi guys I am quit confused n i have some problem that i really need some one 2 solve them and 4 me
the first prob
1. A one dimensional infinite potential well with a width of 12A contains an electron.
a. Calculate the first two energy levels that the electron may occupy
b. If an electron drops from the second energy level to the first, what is the
wavelength of a photon that might be emitted?2nd one
If the temperature is 300K, determine the number of energy states available in GaAs
between:
a. Ec and Ec+kT
b. Ev-kT and Evand the last one
Plot the function for Fermi-Dirac distribution for eV E E eV
F − 0.5 ≤ ( − ) ≤ 0.5 for:
a. T=200K
b. T=300K
c. T=400K
thanx
