Recent previous studies have shown that there is a correlation between heat conductivity and surface materials. In this project, the heat conductivity 3 different samples of T2 copper with different surface roughness was studied. This was done by measuring the temperature of the samples at 9 different point using SOLTEQ Heat Conduction Study Bench...

... The surface roughness of the specimen was achieved using a BUEHLER Handimet Roll Grinder grinding machine with different grits to achieve different surface roughness. The surface roughness of the specimen was measured using a Mitutoyo surftest SJ-410 machine ( Figure 2). The machine measures and calculate the surface roughness using a probe where the average toughness, Ra calculate using arithmetic average (AA) where the total of the absolute values of all areas above and below the average line and then divided by the sampling length Figure 3. Higher AA value means a rougher surface. ...

The presented work describes a modified technique for numerical modeling the characteristics of contact pairs in technical systems, based on the use of microgeometry parameters of contacting surfaces. The microgeometry parameters of the contacting surfaces are determined according to the measurements of their roughness profile. The described techni...
We present measurements of in-plane thermal and electrical conductivity in thermally evaporated gold thin-film samples ranging in thickness from ≈20 to >300nm, performed using a micromachined silicon-nitride membrane thermal isolation platform. In both ≈300-nm-thick films grown in a single Au deposition and a sample built up to >300nm by many seque...
For highly efficient thermoelectric devices with Si nanostructures, we have fabricated and characterized micro/nanometer-scaled Si wires preserving the phonon-drag effect in order to observe the impact of phonon-boundary scattering on the phonon-drag factor in its Seebeck coefficient. The observed phonon-drag factor in the Seebeck coefficient decre...
Hexagonal boron nitride (h-BN) is unique among two-dimensional materials, with a large band gap (~6 eV) and high thermal conductivity (>400 W/m/K), second only to diamond among electrical insulators. Most electronic studies to date have relied on h-BN exfoliated from bulk crystals; however, for scalable applications the material must be synthesized...
