James Spencer Lundh,Bikramjit Chatterjee,Yiwen Song,Albert G. Baca,Robert Kaplar,Thomas E. Beechem,Andrew A. Allerman,Andrew M. Armstrong,Brianna Klein,Anushka Bansal,Disha Talreja,Alexej Pogrebnyakov,Eric R. Heller,Venkatraman Gopalan,Joan M. Redwing,Brian M. Foley,Sukwon Choi +16 more
TL;DR: In this article, a multidimensional thermal characterization of an Al0.30Ga0.70N channel high electron mobility transistor (HEMT) was done using Raman spectroscopy and thermoreflectance thermal imaging to experimentally determine the lateral and vertical steady-state operating temperature profiles.
Journal ArticleDOI
Achieving Minimal Heat Conductivity by Ballistic Confinement in Phononic Metalattices
Weinan Chen,Disha Talreja,Devon Eichfeld,Pratibha Mahale,Nabila Nabi Nova,Hiu Yan Cheng,Jennifer L. Russell,Shih Ying Yu,Nicolas Poilvert,Gerald D. Mahan,Suzanne E. Mohney,Vincent H. Crespi,Thomas E. Mallouk,John V. Badding,Brian M. Foley,Venkatraman Gopalan,Ismaila Dabo +16 more
TL;DR: This study addresses the thermal properties of silicon metalattices that consist of a periodic distribution of spherical inclusions with radii from 7 to 30 nm, embedded into silicon by elucidating the scaling laws that dictate ballistic heat transport at the nanoscale in silicon and other semiconductors.
Journal ArticleDOI
Conformal coating of amorphous silicon and germanium by high pressure chemical vapor deposition for photovoltaic fabrics
Xiaoyu Ji,Hiu Yan Cheng,Alex J. Grede,Alex Molina,Disha Talreja,Suzanne E. Mohney,Noel C. Giebink,John V. Badding,Venkatraman Gopalan +8 more
TL;DR: In this paper, a high pressure chemical vapor deposition process was employed to conformally coat the individual fibers of several types of flexible fabrics (cotton, carbon, steel) with electronically or optoelectronically active materials.
Journal ArticleDOI
Interdependence of Electronic and Thermal Transport in Al x Ga 1–x N Channel HEMTs
Bikramjit Chatterjee,Andrew M. Armstrong,Brianna Klein,Anushka Bansal,Hamid Reza Seyf,Disha Talreja,Alexej Pogrebnyakov,Eric R. Heller,Venkatraman Gopalan,Asegun Henry,Joan M. Redwing,James Spencer Lundh,Brian M. Foley,Sukwon Choi,Yiwen Song,Daniel Shoemaker,Albert G. Baca,Robert Kaplar,Thomas E. Beechem,Christopher B. Saltonstall,Andrew A. Allerman +20 more
TL;DR: In this article, the thermal conductivity, contact resistivity, and channel mobility were characterized as a function of temperature to understand and compare the heat generation profile and electro-thermal transport within these devices.
Journal ArticleDOI
Selectively-Grown Quantum Dot Active Region Lasers
TL;DR: In this paper , a wide distribution of QD thickness variations correlates well to the observed broad photoluminescence (PL) emission linewidths, based on the simulated range of QDs transitions.
