Performance of High Efficiency Avalanche Poly-SiGe Devices for Photo-Sensing Applications
Sensors, 2022 This paper explores poly-silicon-germanium (poly-SiGe) avalanche photo-sensors (APSs) involving a device of heterojunction structures. A low pressure chemical vapor deposition (LPCVD) technique was used to deposit epitaxial poly-SiGe thin films. The thin

Taking Responsibility for Responsibility [PDF]
Public Health Ethics, 2019 AbstractGovernments, physicians, media and academics have all called for individuals to bear responsibility for their own health. In this article, I argue that requiring those with adverse health outcomes to bear responsibility for these outcomes is a bad basis for policy.

Ultraviolet Response in Coplanar Silicon Avalanche Photodiodes with CMOS Compatibility
Sensors, 2022 Highly sensitive ultraviolet (UV) photodetectors are highly desired for industrial and scientific applications. However, the responsivity of silicon photodiodes in the UV wavelength band is relatively low due to high-density Si/SiO2 interface states.
