A low-temperature dynamic mode scanning force microscope operating in high magnetic fields
, 1999 A scanning force microscope was implemented operating at temperatures below 4.2K and in magnetic fields up to 8T. Piezoelectric quartz tuning forks were employed for non optical tip-sample distance control in the dynamic operation mode. Fast response was

Advanced Functional Materials, EarlyView.A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Sen'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

Vibrational assignments and line shapes in inelastic tunnelling spectroscopy: H on Cu(100)
, 2006 We have carried out a computational study of the inelastic electron tunneling spectrum (IETS) of the two vibrational modes of a single hydrogen atom on a Cu(100) surface in a scanning tunneling microscopy (STM) junction.

Exact location of dopants below the Si(001):H surface from scanning tunnelling microscopy and density functional theory [PDF]
, 2017 Control of dopants in silicon remains the most important approach to tailoring the properties of electronic materials for integrated circuits, with Group V impurities the most important n-type dopants.

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Optimal geometry for a quartz multipurpose SPM sensor
Beilstein Journal of Nanotechnology, 2013 We propose a geometry for a piezoelectric SPM sensor that can be used for combined AFM/LFM/STM. The sensor utilises symmetry to provide a lateral mode without the need to excite torsional modes.
