1 Stringfellow, Gerald B.; Zhu, Jing Yi; Liu, FengDual-surfactant effect to enhance p-type doping in III-V semiconductor thin filmsSurfactant effects are usually achieved by the addition of a single surface element. We demonstrate by first-principles calculations a dual-surfactant effect of Sb and H on enhancing Zn doping in organometallic vapor phase epitaxially grown GaP thin films. The combined effects of Sb and H lower sig...Surfactants; p-type doping2008-11
2 Liu, FengTheory of directed nucleation of strained islands on patterned substratesWe develop a theoretical model to elucidate the nucleation of strained islands on patterned substrates. We show that island nucleation is directed to the preferred sites by a much lower energy barrier and smaller critical size. Strain relaxation directs island nucleation to the bottom of a pit rat...Directed nucleation; Strained islands; Patterned substrates2008-11
3 Freire, Juliana; Silva, Claudio T.VisComplete: automating suggestions for visualization pipelinesBuilding visualization and analysis pipelines is a large hurdle in the adoption of visualization and workflow systems by domain scientists. In this paper, we propose techniques to help users construct pipelines by consensus-automatically suggesting completions based on a database of previously creat...VisComplete; Workflows; Auto completion; Visualization pipelines2008-11
4 Harrison, Reid R.Wireless integrated circuit for 100-channel neural stimulationWe present the design of an integrated circuit for wireless neural stimulation, along with bench-top and in-vivo experimental results. The chip has the ability to drive 100 individual stimulation electrodes with constant-current pulses of varying amplitude, duration, interphasic delay, and repetiti...Wireless; Integrated Neural Interface; Neural recording; Telemetry2008-11
5 Harrison, Reid R.Wireless neural interface for chronic recordingA primary goal of the Integrated Neural Interface Project (INIP) is to develop a wireless, implantable device capable of recording neural activity from 100 micromachined electrodes. The heart of this recording system is a low-power integrated circuit that amplifies 100 weak neural signals, detect...Integrated Neural Interface; Wireless; Neural recording; Telemetry2008-11
