This paper presents the development of a transient thermal model of the EVO Electric AFM 140 Axial Flux Permanent Magnet (AFPM) machine based on a hybrid finite difference and lumped parameter method. A maximum deviation between simulated and measured temperature of 2.4°C is recorded after using a Monte Carlo simulation to optimise model parameters representing a 53% reduction in temperature de...

Thermal rectification is a physical phenomenon where the resistance to heat flow is dependent on the sign of the temperature difference across a solid. This effect could be a useful phenomena to many industries if it could be controlled and optimized. However, experimental evidence shows that thermal rectification is dependent on a large number of competing factors. In addition, theoretical mod...

Self-assembled monolayers (SAMs) have recently garnered much interest due to their unique electrical and chemical properties. The limited literature detailing SAM thermal properties has suggested that thermal boundary conductance (TBC) at solid-SAM junctions is not only low, but also insensitive to changes in SAM length as the number of methylene groups (-CH2-) along alkanedithiol chains is var...

We study the thermal transport in two-dimensional systems with a nontrivial Berry curvature texture. The physical realizations are many; for the sake of definiteness, we consider undoped graphene gapped by the presence of an aligned hexagonal-boron-nitride substrate. The same phenomenology applies, i.e., to surface states of 3D topological insulators in the presence of a uniform magnetization. ...

Carbon nanotube (CNT) arrays can be effective thermal interface materials with high compliance and conductance over a wide temperature range. Here, we study CNT interface structures in which free CNT ends are bonded using Pd hexadecanethiolate, Pd(SC16H35)2, to an opposing substrate (one-sided interface) or opposing CNT array (two-sided interface) to enhance contact conductance while maintainin...

This paper describes a thermal imaging system which includes a customized micromachined thermal probe and circuit interface for a scanning microscopy instrument. The probe shank is made from polyimide for mechanical compliance and high thermal isolation, and has a thin-film metal tip of ≈50 nm in diameter. The circuit provides closed-loop control of the tip temperature and also permits it to be...
