Patent
Lattice-Mismatched Semiconductor Structures with Reduced Dislocation Defect Densities and Related Methods for Device Fabrication
Anthony J. Lochtefeld,Matthew T. Currie,Zhiyuan Cheng,James Fiorenza,G. Braithwaite,T. A. Langdo +5 more
TL;DR: In this paper, the fabrication of monolithic lattice-mismatched semiconductor heterostructures with limited area regions having upper portions substantially exhausted of threading dislocations is discussed.
Patent
InP-Based Transistor Fabrication
TL;DR: In this paper, a dielectric layer may be deposited by ALD over a semiconductor layer including In and P. A channel layer is formed above a buffer layer having a lattice constant similar to a InP.
Patent
Quantum Tunneling Devices and Circuits with Lattice-Mismatched Semiconductor Structures
Zhiyuan Cheng,Calvin Sheen +1 more
TL;DR: In this article, a tunneling device is constructed over first and second lattice mismatched semiconductor materials, which is then disposed over the lattice-mismatched materials.
Patent
Photovoltaics on silicon
TL;DR: In this paper, a photovoltaic cell is disposed above a non-crystalline mask layer over a substrate, and the mask is replaced by a polysilicon mask layer.
Patent
Semiconductor sensor structures with reduced dislocation defect densities and related methods for the same
TL;DR: In this article, complementary metal-oxide-semiconductor photodetectors are formed on a silicon substrate by incorporating an aspect-ratio-trapping technique, which can have relatively large micron dimensions.
