TL;DR: This work provides a method to fabricate high-quality silicene and an explanation for the formation of the buckled silicenes sheet.
Theories of scanning probe microscopes at the atomic scale
TL;DR: In this article, the authors discuss and compare the present status of computational modeling of two of the most popular SPM methods (scanning tunneling microscopy and scanning force microscopy) in conjunction with their applications to studies of surface structure and properties with atomic resolution.
Field regulation of single-molecule conductivity by a charged surface atom

TL;DR: This work finds that the onset of molecular conduction is shifted by changing the charge state of a silicon surface atom, or by varying the spatial relationship between the molecule and that charged centre, which results in conductivity changes of substantial magnitude.

Pushing and pulling a Sn ion through an adsorbed phthalocyanine molecule.
TL;DR: A design of molecular layers is presented which enables bistable switching on a surface and, for the first time, control of a single switch in a dense and ordered array at the spatial limit is demonstrated.

Challenges and errors: interpreting high resolution images in scanning tunneling microscopy
TL;DR: In this article, the authors compare experiments and simulations of a scanning tunneling microscope (STM) system and conclude that the combination of first-principle simulations with high-resolution measurements was decisive to arrive at consistent results.
