| Title: | Optical control on HEMT devices | Authors: | Hwee Har Lim Alphones, A. |
Issue Date: | 2001 | Citation: | Hwee Har Lim,Alphones, A. (2001). Optical control on HEMT devices. IEEE Antennas and Propagation Society, AP-S International Symposium (Digest) 2 : 518-520. ScholarBank@NUS Repository. | Abstract: | Theoretical work for the DC characteristics of depletion mode Al0.3Ga0.7As/GaAs HEMT's under optical illumination is presented. Both the photoconductive effect, which increases the 2-DEG channel electron concentration, and the photovoltaic effect in the gate junction are discussed. Analysis of the effect of optical control on the gain of a HEMT amplifier and the optical tuning of a HEMT oscillator are further described. | Source Title: | IEEE Antennas and Propagation Society, AP-S International Symposium (Digest) | URI: | http://scholarbank.nus.edu.sg/handle/10635/112359 | ISSN: | 15223965 |
