Enhanced conductance response in radio frequency scanning tunnelling microscopy [PDF]

open access: yesScientific Reports, 2022
Diverse spectroscopic methods operating at radio frequency depend on a reliable calibration to compensate for the frequency dependent damping of the transmission lines.

Combining high-resolution scanning tunnelling microscopy and first-principles simulations to identify halogen bonding [PDF]

open access: yesNature Communications, 2020
Scanning tunnelling microscopy (STM) is commonly used to study 2D molecular self-assembly but is not always enough to fully solve a supramolecular structure.

Nano-contact microscopy of supracrystals [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2015
Background: Highly ordered three-dimensional colloidal crystals (supracrystals) comprised of 7.4 nm diameter Au nanocrystals (with a 5% size dispersion) have been imaged and analysed using a combination of scanning tunnelling microscopy and dynamic force

Automated collection and categorisation of STM images and STS spectra with and without machine learning [PDF]

open access: yesBeilstein Journal of Nanotechnology
Atomic resolution scanning probe microscopy, and in particular scanning tunnelling microscopy (STM) allows for high-spatial-resolution imaging and also spectroscopic analysis of small organic molecules.

On-surface synthesis of aligned functional nanoribbons monitored by scanning tunnelling microscopy and vibrational spectroscopy [PDF]

open access: yesNature Communications, 2017
On-surface synthesis, in which molecular units assemble and couple on a defined surface, can access rare reaction pathways and products. Here, the authors synthesize functionalized organic nanoribbons on the Ag(110) surface, and monitor the evolution of ...

The effect of lateral π-extension on azulene-based molecules on surface studied by LT-STM [PDF]

open access: yesScientific Reports
Azulene-based systems offer a robust platform for exploring molecular self-assembly and electronic properties on surfaces due to their non-benzenoid topology and dipolar structure.

An experimental demonstration of irreversible mesoscopic carrier transport phenomena in InGaN quantum wells [PDF]

open access: yesScientific Reports
Light-induced carrier transport in mesoscopic systems exhibits a complex interplay between classical and quantum phenomena. Through direct spectroscopic measurements of optoelectronic energy transport in semiconductor quantum wells, we reveal the ...

Scanning tunneling microscopy [PDF]

open access: yesProceedings of the National Academy of Sciences, 1987
A scanning tunneling microscope (STM) can provide atomic-resolution images of samples in ultra-high vacuum, moderate vacuum, gases including air at atmospheric pressure, and liquids including oil, water, liquid nitrogen, and even conductive solutions.

Lightwave-driven scanning tunnelling spectroscopy of atomically precise graphene nanoribbons

open access: yesNature Communications, 2021
Here, the authors perform lightwave-driven terahertz scanning tunnelling microscopy and spectroscopy of graphene nanoribbons with atomic resolution in three dimensions, revealing localized wavefunctions that are inaccessible by conventional scanning ...

Molecular, morphological and functional properties of tunnelling nanotubes between normal and cancer urothelial cells: New insights from the in vitro model mimicking the situation after surgical removal of the urothelial tumor

open access: yesFrontiers in Cell and Developmental Biology, 2022
Tunnelling nanotubes (TNTs) are membranous connections that represent a unique type of intercellular communication in different cell types. They are associated with cell physiology and cancer pathology.
