Site specific focused ion beam preparation and atom probe tomography investigation of semiconductor n

Corwin Pavilion, University Center, UC Santa Barbara
10/25/2017 12PM ESB 1001

Na flux grown bulk GaN crystals at UCSB with a focus on impurities and their effect on the crystal transparency

10/18/2018 12PM ESB 1001

The material properties of III-Nitrides make this platform an excellent choice for power switching applications.

10/4/2018 12PM ESB 1001

Understanding efficiency loss mechanisms and electron transport in InGaN/GaN LEDs by electron emission spectroscopy

5/24/2018 12PM ESB 1001

In this presentation, I will first talk about development of MOCVD-grown TJ contacts on LED test structures. Effects of doping concentration and surface treatments will be discussed based on electrical characteristics and secondary ion mass spectrometry (SIMS) data.

5/8/2018 12PM ESB 1001

Solid-state lighting (SSL) utilizes a semiconductor-based emitter instead of plasma or a filament and is more energy efficient than traditional sources.

5/2/2018 3PM ESB 1001

You are cordially invited to a lecture and reception honoring the recipient of the Fred and Linda R.

5/1/2018 12PM ESB 1001

Deep UV LEDs in the range of 260-280 nm are needed to develop new disinfection and biotechnology applications. UV LEDs are expected to replace Mercury-vapor lamps.

2/14/2018 12PM ESB 1001

In the first part of this talk, we report our progress towards improved light extraction engineering in freestanding semipolar LEDs using Langmuir-Blodgett lithography to create micro-roughened scattering interfaces.

1/25/2018 12PM ESB 1001

In this talk, I will present the first demonstration of continuous-wave (CW) operation of nonpolar GaN-based VCSELs.
