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 …

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 …

Spatially resolved vibrational mapping of nanostructures is indispensable to the
development and understanding of thermal nanodevices, modulation of thermal transport …

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 …

Atomic and single-molecule junctions represent the ultimate limit to the miniaturization of
electrical circuits. They are also ideal platforms for testing quantum transport theories that …

The thermal conductance of a single channel is limited by its unique quantum value GQ, as
was shown theoretically in 1983. This result closely resembles the well-known quantization …

The control of heat conduction through the manipulation of phonons as coherent waves in
solids is of fundamental interest and could also be exploited in applications, but coherent …

The physics of mesoscopic electronic systems has been explored for more than 15 years.
Mesoscopic phenomena in transport processes occur when the wavelength or the …

The breakdown of translational symmetry at heterointerfaces leads to the emergence of new
phonon modes localized at the interface. These modes have an essential role in thermal …

Energy dissipation is a fundamental process governing the dynamics of physical, chemical
and biological systems. It is also one of the main characteristics that distinguish quantum …
