Journal ArticleDOI
Aluminum nitride nanowire light emitting diodes: Breaking the fundamental bottleneck of deep ultraviolet light sources
Songrui Zhao,A. T. Connie,M. H. T. Dastjerdi,Xianghua Kong,Qingxiao Wang,Mehrdad Djavid,Sharif Md. Sadaf,Xianhe Liu,Ishiang Shih,Hong Guo,Zetian Mi +10 more
TL;DR: By carefully tuning the synthesis conditions, a record IQE of 80% can be realized with N-polar AlN nanowire LEDs with emission wavelengths covering the UV-B/C bands, which is nearly ten times higher compared to high quality planar AlN.
Journal ArticleDOI
Full-Color Single Nanowire Pixels for Projection Displays.
Yong-Ho Ra,Renjie Wang,Steffi Y. Woo,Mehrdad Djavid,Sharif Md. Sadaf,Jaesoong Lee,Gianluigi A. Botton,Zetian Mi +7 more
TL;DR: The monolithic integration of full-color LEDs on a single chip, coupled with the capacity to tune light emission characteristics at the single nanowire level, provides an unprecedented approach to realize ultrasmall and efficient projection display, smart lighting, and on-chip spectrometer.
Journal ArticleDOI
An AlGaN Core–Shell Tunnel Junction Nanowire Light-Emitting Diode Operating in the Ultraviolet-C Band
TL;DR: It is demonstrated that critical issues can be potentially addressed by using nearly defect-free AlGaN tunnel junction core-shell nanowire heterostructures, which exhibit high photoluminescence efficiency in the UV-C band at room temperature and nearly one order of magnitude reduction in the device resistance.
Journal ArticleDOI
Engineering the Carrier Dynamics of InGaN Nanowire White Light-Emitting Diodes by Distributed p -AlGaN Electron Blocking Layers
Hieu Pham Trung Nguyen,Mehrdad Djavid,Steffi Y. Woo,Xianhe Liu,A. T. Connie,Sharif Md. Sadaf,Qi Wang,Gianluigi A. Botton,Ishiang Shih,Zetian Mi +9 more
TL;DR: This work reports on the demonstration of a new type of axial nanowire LED heterostructures, with the use of self-organized InGaN/AlGaN dot-in-a-wire core-shell Nanowire arrays, which is found to be more effective in reducing electron overflow, compared to the conventional AlGaN EBL.
Journal ArticleDOI
Diode-less bilayer oxide (WOx?NbOx) device for cross-point resistive memory applications
Xinjun Liu,Sharif Md. Sadaf,Myungwoo Son,Jungho Shin,Jubong Park,Joonmyoung Lee,Sangsu Park,Hyunsang Hwang +7 more
TL;DR: It is shown that electroformed W-NbO(x)-Pt devices can simultaneously exhibit both threshold switching and memory switching.
