Journal ArticleDOI
Anisotropic and inhomogeneous thermal conduction in suspended thin-film polycrystalline diamond
Aditya Sood,Jungwan Cho,Jungwan Cho,Karl D. Hobart,Tatyana I. Feygelson,Bradford B. Pate,Mehdi Asheghi,David G. Cahill,Kenneth E. Goodson +8 more
TL;DR: In this article, the authors studied the thermal conduction in suspended polycrystalline diamond films, with thickness ranges between 0.5 and 5.6 μm, using time-domain thermoreflectance.
Journal ArticleDOI
Control of the in-plane thermal conductivity of ultra-thin nanocrystalline diamond films through the grain and grain boundary properties
Julian Anaya,Stefano Rossi,Mohammed Alomari,Erhard Kohn,Lajos Tóth,Béla Pécz,Karl D. Hobart,Travis J. Anderson,Tatyana I. Feygelson,Bradford B. Pate,Martin Kuball +10 more
TL;DR: In this article, the in-plane thermal conductivity of polycrystalline diamond near its nucleation site, which is a key parameter to an efficient integration of diamond in modern high power AlGaN/GaN high electron mobility devices, has been studied.
Journal ArticleDOI
Simultaneous determination of the lattice thermal conductivity and grain/grain thermal resistance in polycrystalline diamond
Julian Anaya,Tingyu Bai,Yinmin Wang,Chao Li,Mark S. Goorsky,Thomas L. Bougher,Luke Yates,Zhe Cheng,Samuel Graham,Karl D. Hobart,Tatyana I. Feygelson,Marko J. Tadjer,Travis J. Anderson,Bradford B. Pate,Martin Kuball +14 more
TL;DR: In this paper, the inplane and cross-plane thermal conductivity of polycrystalline diamond near its nucleation region have been measured by Raman thermography assisted by TiO 2 nanoparticles and by picosecond time-domain thermoreflectance (TDTR).
Journal ArticleDOI
Integration of polycrystalline Ga2O3 on diamond for thermal management
Zhe Cheng,Virginia D. Wheeler,Tingyu Bai,Jingjing Shi,Marko J. Tadjer,Tatyana I. Feygelson,Karl D. Hobart,Mark S. Goorsky,Samuel Graham +8 more
TL;DR: In this paper, the authors measured the thermal boundary conductance (TBC) of the Ga2O3-diamond interfaces with different interface pretreatments and showed that a high TBC can be obtained from strong interfacial bonds across the interfaces.
Journal ArticleDOI
Tunable Thermal Energy Transport across Diamond Membranes and Diamond-Si Interfaces by Nanoscale Graphoepitaxy.
