Electric field

A physical field present around an electrically charged particle that exerts a force on all other charged particles is called an electric field. The charged particles present in the field either repel or attract. From electric charges or time-varying magnetic fields, the electric field originates. One of the manifestations of electromagnetic force which is one of the four fundamental forces present in nature are the electric fields and magnetic fields.

QUESTION 4 The energy gap of GaP is 2.26 eV. Show that partial absorption of visible light is a) occurred when GaP wafer exposed to visible light, and the materials appears reddish. For visible light, the photon energy is in the range of 1.8 – 3.1 eV. In some semiconductor material the bottom of conduction band does not lie at the b) origin (k + 0). For the absorption process, the electrons absorb the photon and phonon simultaneously to make a transition from valence band to conduction band. Given the wavelength of photon is 2- 10°m and for optical phonon the wavelength is 2~10-9m, respectively. Using the calculated values of energy and momentum of phonon and photon, explain the main roles of photon and phonon for the transition proses. (Given phonon velocity, Vph = 3000 ms-', speed of light, c = 3 x 108 ms1 and Plank constant, h= 4.1357 x 10-15 eVs)
