Electronic and structural characterisation of polycrystalline platinum disulfide thin films
(2020)We employ a combination of scanning tunnelling microscopy (STM) and scanning tunnelling spectroscopy (STS) to investigate the properties of layered PtS2, synthesised via thermally assisted conversion (TAC) of a metallic ... -
Imaging and identification of point defects in PtTe2
(2021)The properties and performance of two-dimensional (2D) materials can be greatly affected by point defects. PtTe2, a 2D material that belongs to the group 10 transition metal dichalcogenides, is a type-II Dirac semimetal, ... -
Local chemical composition of nanophase-separated polymer brushes
(2011)Using scattering scanning nearfield infrared microscopy (s-SNIM), we have imaged the nanoscale phase separation of mixed polystyrenepoly(methyl methacrylate) (PSPMMA) brushes and investigated changes in the top layer as a ... -
Smart polymer surfaces: mapping chemical landscapes on the nanometre scale
(Royal Society of Chemistry, 2010)We show that Scattering Infrared Near-field Microscopy (SNIM) allows chemical mapping of polymer monolayers that can serve as designed nanostructured surfaces with specific surface chemistry properties on a nm scale. ...
