Growth of Sr1-xCaxRuO3 thin films by metalorganic aerosol deposition [PDF]

, 2009
We report the growth of thin films of Sr1-xCaxRuO3 on SrTiO3 and MgO substrates by metalorganic aerosol deposition. The structure and microstructure is characterized by X-ray diffraction and room-temperature scanning tunnelling microscopy (STM ...

Scanning Tunneling Microscopy

Hyomen Kagaku, 1984
A new technique developed by Binning, Rohrer, Gerber and Weibel on scanning tunneling micro scopy (STM) is presented. STM gives surface topographies in real space and work function profiles on an atomic scale. The spatial resolution of STM is sub-A in depth and several A in lateral direction.

A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

Advanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Tip effects in scanning tunnelling microscopy of atomic-scale magnetic structures

, 2001
The spin-polarized scanning tunnelling microscope (STM) can in principle resolve not only the electronic, but also the magnetic surface structure. We model recent STM measurements achieving magnetic resolution on the atomic scale by a first-principles ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Landau Quantization in Graphene Monolayer, Bernal Bilayer, and Bernal Trilayer on Graphite Surface

, 2015
Electronic properties of surface areas decoupled from graphite are studied using scanning tunnelling microscopy and spectroscopy. We show that it is possible to identify decoupled graphene monolayer, Bernal bilayer, and Bernal trilayer on graphite ...

Shape‐Controlled Guanine Self‐Assemblies for Stable and Fast‐Ion Solid–Electrolyte Interphases in Sustainable Li Metal Batteries

Advanced Functional Materials, EarlyView.
The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

Transport characteristics of a silicene nanoribbon on Ag(110)

Beilstein Journal of Nanotechnology, 2017
We present the transport characteristics of individual silicene nanoribbons (SiNRs) grown on Ag(110). By lifting up a single SiNR with a low-temperature scanning tunneling microscope tip, a nanojunction consisting of tip, SiNR and Ag is fabricated.
