Hydrostatic Pressure Investigations of Quantum-Well Optoelectronic Devices
- 135 Downloads
Quantum wells and superlattices offer exciting new possibilities for engineering the electronic band structure of semiconductor optoelectronic devices. Hydrostatic pressure also causes changes in the band structure which in many respects mimic the effects of quantum confinement and hence allows a systematic study to be made by varying the pressure on a single device. This avoids unwanted chemical changes that can occur when the band structure is varied in a growth sequence and thus allows parameters dependent only on the band structure to be clearly identified.
