Deterministic assembly of microdevices by transfer-printing is an advanced manufacturing technology that enables the heterogeneous integration of disparate materials on largearea substrates. [ 1–5 ] All active electronic devices generate heat as a byproduct of their operation and thermal management of transfer-printed assemblies must be a consideration whenever the heat fl ux is large. While th...

In this paper, we studied heat transfer properties of a single tin dioxide nanobelt using non-contact high resolution thermoreflectance imaging technique. Temperature difference across the nanobelt was created by attaching its both ends to a microfabricated thin film heater and sensor pair. High resolution thermal images of the nanobelt and thin film devices were obtained at variant pulsing cur...

Thermal and electrical transport in a new class of nanocomposites composed of random isotropic two-dimensional ensembles of nanotubes or nanowires in a substrate (host matrix) is considered for use in the channel region of thin-film transistors (TFTs). The random ensemble of nanotubes is generated numerically and each nanotube is discretized using a finite volume scheme. To simulate transport i...

Continued reduction in characteristic dimensions in nanosystems has given rise to increasing importance of material interfaces on the overall system performance. With regard to thermal transport, this increases the need for a better fundamental understanding of the processes affecting interfacial thermal transport, as characterized by the thermal boundary conductance. When thermal boundary cond...

A theoretical and experimental parametric study of the heat-transfer phenomena on a multistage passive cryogenic radiator is presented. This investigationwas performed in the frame of a cooperative effort between Clemson University and the Federal University of Santa Catarina. Passive cryogenic radiator technology is under development at the Satellite Thermal Control Laboratory at the Federal U...

The impact of surface roughness on conductive heat transfer across nanoscale contacts is investigated by means scanning thermal microscopy. Silicon surfaces with the out-of-plane rms ∼0, 0.5, 4, 7, and 11 nm are scanned both under air vacuum conditions. Three types resistive SThM probes spanning curvature radii over orders magnitude used. A correlation between conductance adhesion force highlig...

A multi-layer photonic crystal can be used to suppress coherent thermal conductance below the vacuum conductance value, over the entire high-temperature range. With interlacing layers of silicon and vacuum, heat can only be carried by photons. The thermal conductance of the crystal would then be determined by the photonic band structure. Partial photonic band gaps that present over most of the ...
