Inelastic Electron Tunneling Spectroscopy

Inelastic electron tunneling spectroscopy for topological insulators.

Inelastic electron tunneling spectroscopy is a powerful spectroscopy that allows one to investigate the nature of local excitations and energy transfer in the system of interest. We study inelastic electron tunneling spectroscopy for topological insulators and investigate the role of inelastic scattering on the Dirac node states on the surface of topological insulators. Local inelastic scatteri...

Current image tunneling spectroscopy of boron-doped nanodiamonds

The electron field emission properties of the nanodiamond films were examined using scanning tunneling microscopic sSTMd technique. Current image tunneling spectroscopic measurements reveal the direct dependence of electron tunneling/field emission behavior of the films on the proportion of grain boundaries present. Local tunneling current-voltage sIt–Vd measurements show that incorporation of ...

Tunneling spectroscopy and vortex imaging in boron-doped diamond.

We present the first scanning tunneling spectroscopy study of single-crystalline boron-doped diamond. The measurements were performed below 100 mK with a low temperature scanning tunneling microscope. The tunneling density of states displays a clear superconducting gap. The temperature evolution of the order parameter follows the weak-coupling BCS law with Delta(0)/kBTc approximately 1.74. Vort...

Spin-flip inelastic electron tunneling spectroscopy in atomic chains

We present a theoretical study of the spin transport properties of monoatomic magnetic chains with a focus on the spectroscopical features of the I -V curve associated with spin-flip processes. Our calculations are based on the s-d model for magnetism with the electron transport treated at the level of the nonequilibrium Green’s function formalism. Inelastic spin-flip scattering processes are i...
