In this paper, a low-temperature ultra-high-vacuum (UHV) scanning tunneling microscope setup with a combination of a solenoid and a split-pair magnet is presented.Abstract:
We present a new design of a low-temperature ultrahigh-vacuum (UHV) scanning tunneling microscope setup with a combination of a solenoid and a split-pair magnet The scanning tunneling microscope can be operated at temperatures down to 8 K and in a rotatable magnetic field of up to 1 T Magnetic fields of up to 7 T perpendicular and 2 T parallel to the sample surface can be applied The UHV part of the system allows in situ preparation and low energy electron diffraction/Auger analysis of samples First topographic and spectroscopic measurements on p-InAs(110) are presentedread more

TL;DR: The spectral resolution capabilities with tunneling spectroscopy results obtained on an epitaxial graphene sample resolving the quantum Landau levels in a magnetic field, including the sublevels corresponding to the lifting of the electron spin and valley degeneracies are shown.

TL;DR: First direct real-space images of spin-split molecular orbitals of a single-molecule magnet adsorbed on a ferromagnetic nanostructure are presented and the magnitude of the spin-splitting as well as the charge state of the adsorbing molecule is determined.

Scanning Tunneling Spectroscopy
TL;DR: For many years, STM lacked chemical specificity; however, the recent development of STM-IETS (inelastic electron tunneling spectroscopy) has allowed us to measure the vibrational spectrum of a single molecule.

Temperature dependence of the energy gap in semiconductors
TL;DR: In this article, a relation for the variation of the energy gap (E g ) with temperature (T ) in semiconductors is proposed. And the equation satisfactorily represents the experimental data for diamond, Si, Ge, 6H-SiC, GaAs, InP and InAs.

Confinement of electrons to quantum corrals on a metal surface.
TL;DR: Tuning spectroscopy performed inside of the corrals revealed a series of discrete resonances, providing evidence for size quantization and STM images show that the corral's interior local density of states is dominated by the eigenstate density expected for an electron trapped in a round two-dimensional box.
