Photoassisted scanning tunneling microscopy
TL;DR: A review of light-induced effects in tunneling microscopy can be found in this article, where the authors discuss thermal effects, nonlinear effects, field enhancement at the STM tip, various effects on semiconductor surfaces, excitation of surface plasmons, detection of photoelectrons, spin-polarized tunneling, local optical spectroscopy, the use of ultrashort laser pulses for time-resolved STM, and the combination of STM and scanning near-field optical microscopy.

Heat transfer between two metallic surfaces at small distances
TL;DR: In this article, the heat transfer across the vacuum gap between two parallel metallic surfaces, if the gap width is decreased below several microns, has been investigated, and the experimental results and theoretical considerations indicate that heat transfer, based on the discussed proximity mechanism, is very small, smaller than predicted by the theory of Polder and Van Hove.

Atomic-scale mapping of thermoelectric power on graphene: role of defects and boundaries.
TL;DR: The spatially resolved thermoelectric power is studied on epitaxial graphene on SiC with direct correspondence to graphene atomic structures by a scanning tunneling microscopy (STM) method, and variations of thermovoltage are distinguished at defects and boundaries with atomic resolution.

Progress in scanning probe microscopy
TL;DR: In this paper, the development of the key concepts of scanning probe microscopes is reviewed from their early history to current technologies, and some key applications of scanning probes are presented and future advances that are likely to come to fruition in the next decade are discussed.

TL;DR: Here it is shown that local thermoelectric measurements can yield high-sensitivity imaging of structural disorder on the atomic and nanometre scales, and uncovered point defects in the first layer of epitaxial graphene which generate soliton-like domain-wall line patterns separating regions of the different interlayer stacking of the second graphene layer.

Apparent size of an atom in the scanning tunneling microscope as a function of bias.
TL;DR: In this paper, the apparent size of an adsorbed atom was studied as a function of bias voltage for several different atoms, and it was found that this quantity is found to reflect state-density features that lie well above the Fermi level.

Microscopy of chemical-potential variations on an atomic scale
TL;DR: The scanning chemical potential microscope (SCPM) as mentioned in this paper is based on a recently developed tunnelling thermometer, which allows the spatial mapping of thermoelectric potential variations resulting from absorption of light.
