TL;DR: The UWBG semiconductor materials, such as high Al‐content AlGaN, diamond and Ga2O3, advanced in maturity to the point where realizing some of their tantalizing advantages is a relatively near‐term possibility.
Journal ArticleDOI
Thermal effects in packaging high power light emitting diode arrays
Adam Christensen,Samuel Graham +1 more
TL;DR: In this paper, a thermal resistor network model was combined with a 3D finite element submodel of an LED structure to predict system and die level temperatures, and the impact of LED array density, LED power density, and active versus passive cooling methods on device operation was calculated.
Journal ArticleDOI
Electrical, Thermal, and Mechanical Characterization of Silicon Microcantilever Heaters
Jungchul Lee,Thomas E. Beechem,Tanya L. Wright,Brent A. Nelson,Samuel Graham,William P. King +5 more
TL;DR: In this paper, the authors describe detailed mechanical, electrical, and thermal characterization and calibration of AFM cantilevers having integrated solid-state heaters, which have been applied to metrology, thermophysical property measurements, and nanoscale manufacturing.
Journal ArticleDOI
Stability of Doped Transparent Carbon Nanotube Electrodes
TL;DR: In this paper, the effectiveness of p-doping transparent single-walled carbon nanotube (SWNT) films via chemical treatment with HNO 3 and SOCl 2 was evaluated.
