Experimental observation of ballistic to diffusive transition in AlN thin films
Md Shafkat Bin Hoque, Michael E. Liao, Saman Zare +10
Bulk AlN possesses high thermal conductivity due to long phonon mean-free-paths, high group velocity, and long lifetimes. However, the thermal transport scenario becomes very diffe…
Thermal conductivity measurements of sub-surface buried substrates by steady-state thermoreflectance
Md Shafkat Bin Hoque, Yee Rui Koh, Kiumars Aryana +10
Measuring the thermal conductivity of sub-surface buried substrates are of significant practical interests. However, this remains challenging with traditional pump-probe spectrosco…
Experimental Observation of High Intrinsic Thermal Conductivity of AlN
Zhe Cheng, Yee Rui Koh, Abdullah Mamun +17
AlN is an ultra-wide bandgap semiconductor which has been developed for applications including power electronics and optoelectronics. Thermal management of these applications is th…
Thermal Conductance Across Harmonic-matched Epitaxial Al-sapphire Heterointerfaces
Zhe Cheng, Yee Rui Koh, Habib Ahmad +17
A unified understanding of interfacial thermal transport is missing due to the complicated nature of interfaces which involves complex factors such as interfacial bonding, interfac…
Homogenous alloys on ZnO substrates: A new approach for high performance thermoelectric materials
Yining Feng, Evan Witkoske, Bahadir Kucukgok +4
High performance thermoelectric materials for wide-range temperature applications still remains a challenge. In this study, we have produced high-quality homogeneous $In_{0.32}Ga_{…
Superdiffusive heat conduction in semiconductor alloys -- II. Truncated Lévy formalism for experimental analysis
Bjorn Vermeersch, Amr M. S. Mohammed, Gilles Pernot +2
Nearly all experimental observations of quasi-ballistic heat flow are interpreted using Fourier theory with modified thermal conductivity. Detailed Boltzmann transport equation (BT…
