Many quasi-one-dimensional (1D) materials are experimental approximations to the
textbook models of Peierls instabilities and collective excitations in 1D electronic systems …

Several approaches for surface-sensitive conductance measurements are reviewed.
Particular emphasis is placed on nanoscale multi-point probe techniques. The results for two …

The In/Si (111)-(4× 1) surface is a paradigmatic example of a quasi-one-dimensional system
showing a reversible structural and electronic (metal-insulator) phase transition when the …

Abstract Antiferromagnetic-insulating (AF-I) and ferromagnetic-metallic (FM-M) phases
coexist in various half-doped manganites over a range of temperature and magnetic field …

Charge density waves are wave-like modulations of a material's electron density that display
collective amplitude and phase dynamics. The interaction with atomic impurities induces …

Light-control of structural dynamics at surfaces promises switching of chemical and physical
functionality at rates limited only by the velocity of directed atomic motion. Following optical …

Neutron diffraction, Mössbauer spectroscopy, magnetometry, and in-field x-ray diffraction are
employed to investigate the magnetoelastic phase transition in hexagonal (Mn, Fe) 2 (P, Si) …

The structural and electronic properties of the quasi-one-dimensional In/Si (111) surface
system are calculated from first principles. It is found that the symmetry lowering of the In …

Nanoscale phase separation is common in many materials ranging from correlated electron
systems to semiconductor surfaces undergoing phase transitions. On solid surfaces …

We demonstrate the controllable electron doping into metallic atomic wires, indium wires self-
assembled on the Si (111) surface, which feature one-dimensional (1D) band structure and …
