ECE 475 - Optoelectronic and Photovoltaic Devices

3 units (fi 8)(EITHER, 3-0-0)

Basic optical properties of crystalline and amorphous semiconductor materials: energy band diagrams, optical constants. Recombination and light emission in semiconductors. Light emitting diodes: spectral characteristics, materials, and applications. Stimulated emission and laser oscillation conditions in semiconductors. Laser diodes: modal and spectral properties, steady state rate equations, materials and structures. Light absorption, optical to electrical energy conversion. Photovoltaic cells: fill factors and efficiency, temperature effects, alternative materials and structures. Prerequisite: ECE 302 or E E 340. Credit may be obtained in only one of ECE 475 or E E 475.
