Distributed contact flip chip InGaN/GaN blue LED; comparison with conventional LEDs
Genc, M.; Sheremet, V.; Elci, M.; Kasapoglu, A. E.; Altuntas, I.; Demir, I.; Egin, G.; Islamoglu, S.; Gur, Emre; Muzafferoglu, N.; Elagoz, S.; Gulseren, O.; Aydinli, A. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2019)This paper presents high performance, GaN/InGaN-based light emitting diodes (LEDs) in three different device configurations, namely Top Emitting (TE) LED, conventional Flip Chip (FC) and Distributed Contact (DC) FC. Series ... -
Electrical performance of InAs/AlSb/GaSb superlattice photodetectors
Tansel, T.; Hostut, M.; Elagoz, S.; Kilic, A.; Ergun, Y.; Aydinli, A. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)Temperature dependence of dark current measurements is an efficient way to verify the quality of an infrared detector. Low dark current density values are needed for high performance detector applications. Identification ... -
InGaN stress compensation layers in InGaN/GaN blue LEDs with step graded electron injectors
Sheremet, V.; Gheshlaghi, N.; Sozen, M.; Elci, M.; Sheremet, N.; Aydinli, A.; Altuntas, I.; Ding, K.; Avrutin, V.; Ozgur, U.; Morkoc, H. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2018)We investigate the effect of InGaN stress compensation layer on the properties of light emitting diodes based on InGaN/GaN multiple quantum well (MQW) structures with step graded electron injectors. Insertion of an InGaN ... -
The role of ITO resistivity on current spreading and leakage in InGaN/GaN light emitting diodes
Sheremet, V.; Genc, M.; Elci, M.; Sheremet, N.; Aydinli, A.; Altuntas, I.; Ding, K.; Avrutin, V.; Ozgur, U.; Morkoc, H. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017)The effect of a transparent ITO current spreading layer on electrical and light output properties of blue InGaN/GaN light emitting diodes (LEDs) is discussed. When finite conductivity of ITO is taken into account, unlike ... -
