Simulation of sub-nm carrier profiling by scanning frequency comb microscopy

open access: yesAIP Advances, 2019
A mode-locked laser focused on the tunneling junction of a scanning tunneling microscope (STM) superimposes a microwave frequency comb with hundreds of harmonics on the DC tunneling current.

Adsorption of enantiomeric and racemic tyrosine on Cu(111): A scanning tunneling microscopy study

open access: yes, 2003
The adsorption of enantiomers and a racemic mixture of tyrosine (tyr) on Cu(111) has been investigated by cyclic voltammetry and electrochemical scanning tunneling microscopy. D-tyr and L-tyr molecules adsorb on Cu(111) and show a (4 x 4) structure.

Atomic and Electronic Structure of Graphene and Graphene Intercalation Compounds. X-Ray Standing Wave and Scanning Tunnelling Microscopy Studies [PDF]

open access: yes, 2013
The morphology of graphene/Iridium(111) was studied by x-ray standing wave (XSW) measurements. A dependence of the moire corrugation on the graphene coverage is observed.

Scanning Tunneling Microscopy

open access: yesSen'i Gakkaishi, 1988
Publisher Summary Scanning tunneling microscopy (STM) has been finding ever increasing application in surface physics. STM, even as it is used now, has furnished fascinating results, and undoubtedly, holds the greatest promise for surface physics. This is because of its unique resolution that can approach hundreds of angstroms along the normal to the

STM study of self-assembled phthalocyanine derivatives and their hosting properties [PDF]

open access: yes, 2008
Molecular self-assembly, as a most studied case of self-assembly, is one of the few practical strategies for making ensembles of nano- and micro structures. As an essential aspect of the “bottom-up” approach, it is attractive for both scientific research

FRACTAL STRUCTURE OF TITANIUM NITRITE DEPOSITED ON STAINLESS STEEL SUBSTRATE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2014
On the basis of images obtained using scanning tunneling microscope, it was shown that the fractal dimension can be considered as some universal surface characteristic of the titanium nitrite, deposited on stainless steel.
