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 ... -
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 ... -
