Metal diamond composites: Challenges in interface design
Metal-diamond composites have been identified as promising materials for applications in which high thermal conductivity and low coefficient of thermal expansion is required, e.g. applications of thermal management. Besides the intrinsic properties of the ...
2014Thermal boundary conductance between refractory metal carbides and diamond
Christian Monachon, Ludger Weber
The thermal boundary conductance (TBC) between thin films of Cr, Mo, Nb and W and diamond substrates has been measured using time domain thermoreflectance before and after a high-vacuum heat treatment at 800 degrees C for 2 h. While no signs of carbide for ...

Christian Monachon, Ludger Weber
The effect of an Al2O3 interlayer on the thermal conductance of metal (Al)/non-metal (diamond and silicon) interfaces is investigated using Time Domain ThermoReflectance (TDTR). Interlayers between 1.7 and 20 nm are deposited on oxygen-terminated diamond a ...
Wiley-Blackwell2014Thermal Boundary Conductance between metals and dielectrics
This work consists in an experimental study of the main parameters governing the transport of heat across an interface between two solids, when it is dominated by phonons. The main experimental tool used is Time-Domain ThermoReflectance (TDTR), which is an ...

Christian Monachon, Ludger Weber
[100] and [111] oriented diamond substrates were treated using Ar:H and Ar:O plasma treatments, and 1:1 HNO3:H2SO4 heated at 200 ̊C. Subsequent to these treatments, an aluminum layer was either evaporated or sputte- red on the substrates. The Thermal Bound ...
Elsevier2013Effect of a nm-sized interlayer on the Thermal Boundary Conductance between metals and diamond
Study the influence of adjunction of a dielectric or metallic interlayer on the Thermal Boundary Conductance (TBC) measurable between a metallic layer and a diamond substrate. An interlayer does not need to be thick to have a substantial influence influenc ...
2013Thermal boundary conductance of transition metals on diamond
Christian Monachon, Ludger Weber
An experimental process that was used to obtain a direct measurement of Thermal Boundary Conductance (TBC) between a diamond substrate and several transition metals, deposited by sputtering, is described. Using Time-Domain ThermoReflectance (TDTR), the cri ...
