Monolithic Integration of GaN Thin Film and GaN Nanorods Pixels: Facile Growth of InGaN/GaN Quantum Wells for the Realization of Full Color Micro‐LED Display

open access: yesAdvanced Optical Materials, EarlyView.
This work implements an advanced lithographic technique to fabricate a template to exploit the indium incorporation efficiency of crystallographic orientations of GaN and demonstrates green and blue self‐emissive µLED pixels through an integration of MOCVD growth technique, device fabrication and phosphor conversion for the realization of full‐color ...

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

open access: yesAdvanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, EarlyView.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
