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.

Atomic force microscopy and other scanning probe microscopy methods to study nanoscale domains in model lipid membranes

Advances in Physics: X, 2023
The cell membrane is a fundamental biological structure, which is only 6–10 nm thick. It is composed of hundreds of lipid types, which form small and dynamic lipid domains or rafts.

Direct writing of ferroelectric domains on the x- and y-faces of lithium niobate using a continuous wave ultraviolet laser [PDF]

, 2011
Ferroelectric domain reversal has been achieved by scanning a tightly focused, strongly absorbed ultraviolet laser beam across the x- and y-faces of lithium niobate crystals. The domains were investigated by piezoresponse force microscopy.

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]

, 2010
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...
