June 20 - 22, 2012
The Penn Stater - Pennsylvania State University
COMPLETE CONFERENCE DETAILS


The Electronic Materials Conference (EMC) is the premier annual forum on the preparation and characterization of electronic materials. EMC 2012 was held June 20 – 22, at scenic Pennsylvania State University.  The conference featured a plenary session, parallel topical sessions, a poster session and an industrial exhibition. Papers submitted by students were eligible for “Best Student Paper Awards.”

The Electronic Materials Conference was coordinated with the Device Research Conference to be held during the same week from June 18 - 20, 2012. This recognized the strong interaction between device and electronic materials research and provided for fruitful exchange of information between attendees of both conferences.

   Nonpolar and Semipolar GaN Materials and Devices:
The Journey so Far

 

Devices grown on c-plane GaN suffer from large internal electric fields due to discontinuities in spontaneous and piezoelectric polarization effects which cause charge separation between holes and electrons in quantum wells and limits the radiative recombination efficiency.  Nonpolar GaN devices, such as in the m-plane (1100), are free from polarization related electric fields since the polar c-axis is parallel to any heterointerfaces.  Semipolar GaN-based devices have reduced electric fields and in some cases, such as (2021), show a high propensity for Indium update for InGaN quantum wells.

In this talk, we present work on outstanding materials and device opportunities issues and opportunities including:  morphological stability with special emphasis on the role of substrate orientation and growth conditions [1,2,3]; the development of pseudomorphoric InGaN and AlGaN semipolar buffer layers via dislocation strain relaxation [4,5,6,]; blue (1122) LDs in relaxed buffer layers [7]; green LEDs on relaxed buffer layers [8]; new detailed atom probe analysis of high performance GaN-based LEDs and laser diodes [9].  Additionally, we update progress on nonpolar electron devices and nonpolar and semipolar LEDs and LDs including the achievement of high performance true blue (λ >450 nm) and true green (λ >515 nm) lasers on m-plane and semipolar (namely, (2021)) GaN substrates [10,11].  Finally, we will present recent work on polarized light emission from m-plane LEDs [12] and demonstrate the first photonic crystal nonpolar LEDs [13].
