Heat exchange between closely positioned bodies has become an important issue for such
areas of modern technology as integrated circuits, atomic force microscopy, and high …

Heat transfer between bodies separated by nanoscale vacuum gap distances has been
extensively studied for potential applications in thermal management [1, 2], energy …

With increasing interest in nanotechnology, the question arises of how heat is exchanged
between materials separated by only a few nanometers of vacuum. Here, we present …

In vacuum, thermal energy is transported by photons (thermal radiation) but not phonons.
Recent studies, however, indicated that phonon heat transfer across a vacuum gap is …

Phonons (collective atomic vibrations in solids) are more effective in transporting heat than
photons. This is the reason why the conduction mode of heat transport in nonmetals …

In this paper, we analyze the heat transport by acoustic waves in arbitrary layered structures
that may include several vacuum layers. The analysis is based on our prior description of the …

The authors describe how acoustic phonons can directly tunnel through vacuum and,
therefore, transmit energy and conduct heat between bodies that are separated by a vacuum …

Heat transfer in solids is typically conducted through either electrons or atomic vibrations
known as phonons. In a vacuum, heat has long been thought to be transferred by radiation …

Heat is transferred by radiation between two well-separated bodies at temperatures of finite
difference in vacuum. At large distances the heat transfer can be described by black body …

When the separation of two surfaces approaches sub-nanometre scale, the boundary
between the two most fundamental heat transfer modes, heat conduction by phonons and …
