Application of zero-temperature-gradient zero-bias thermally stimulated current spectroscopy to ultrathin high-dielectric-constant insulator film characterization
Previously, we have reported our application of the zero-bias thermally stimulated current (ZBTSC) spectroscopy technique to study defect states in high-dielectric-constant insulator films such as tan...

Phonon-assisted stimulated emission from single CdS nanoribbons at room temperature
We report room-temperature stimulated emission in single CdS nanoribbons obtained through Au-catalyzed physical evaporation route. These ribbons have single-crystal structures and uniform rectangular ...

A manganese nitride surface containing a well-ordered array of MnN-bonded manganese clusters is investigated. The clusters are composed of a quadrant array of Mn atoms forming a tetramer. Scanning tunneling microscopy is used to image and resolve the clusters into their constituent atoms and their structure and arrangement is presented. The Mn–Mn and Mn–N bond lengths are estimated from the experimental data and compared with theoretical predictions by Rao and Jena [Phys. Rev. Lett. 89, 185504 (2002)] for free, N-doped Mn clusters. The possible effect of the bond lengths on the magnetic properties of the clusters is discussed.
