Topographic and electronic structure of cleaved SrTiO3(001) surfaces
Wattaka Sitaputra, Marek Skowronski, Randall M. Feenstra
The topographic and electronic structure of cleaved SrTiO3(001) surfaces were studied, employing samples that either had or had not been coated with Ti on their outer surfaces prio…
Formation of hexagonal Boron Nitride on Graphene-covered Copper Surfaces
Devashish P. Gopalan, Patrick C. Mende, Sergio C. de la Barrera +10
Graphene-covered copper surfaces have been exposed to borazine, (BH)3(NH)3, with the resulting surfaces characterized by low-energy electron microscopy. Although the intent of the…
Theory of resonant tunneling in bilayer-graphene/hexagonal-boron-nitride heterostructures
Sergio C. de la Barrera, Randall M. Feenstra
A theory is developed for calculating vertical tunneling current between two sheets of bilayer graphene separated by a thin, insulating layer of hexagonal boron nitride, neglecting…
Oxygen Vacancies on SrO-terminated SrTiO3(001) Surfaces studied by Scanning Tunneling Spectroscopy
Wattaka Sitaputra, Nikhil Sivadas, Marek Skowronski +2
The electronic structure of SrTiO3(001) surfaces was studied using scanning tunneling spectroscopy and density-functional theory. With high dynamic range measurements, an in-gap tr…
