Document Summary
An electron and a photon traveling in a vacuum have the same value for energy, but the wavelength of the photon is 100 times that wavelength of the electron. a. b. In a 1-d kronig-penney model for electrons, the periodic potential function has the following parameters a = 4 a, b = 0. 1 a, and vo = 12 ev. The semiconductor material as r = 10, e = 2. 277 x10-12 s, h = 4. 554 x10-13 s, e = 0. 8 m2/v-s, h = 0. 05 m2/v-s, me a. b. c. 17 nov - 9 dec page 20 axial field of 1 v/m is applied. An electron and a photon traveling in a vacuum have the same value for energy, but the wavelength of the photon is. 100 times that wavelength of the electron. a. b. Determine the value of the photon wavelength in mks units.
