This manuscript describes a simple and versatile approach to engineering surface roughness gradients via combination of microfluidics and photopolymerization. Through UV-mediated polymerization, ...

In this paper, a novel p-GaN gate HEMT with p-type doping concentration graded termination (PGT-HEMT) is proposed and simulated. The proposed structure improves the breakdown voltage from 622 V to ...

Many chemical and biological processes are dependent on molecular gradients. We describe a new microfluidic approach that can be used to produce spatiotemporal gradients across two-dimensional ...
