Rapid Surface Oxidation as a Source of Surface Degradation Factor for Bi2Se3
Desheng Kong, Judy J. Cha, Keji Lai +8
Bi2Se3 is a topological insulator with metallic surface states residing in a large bulk bandgap. It is believed that Bi2Se3 gets additional n-type doping after exposure to atmosphe…
Ultra-thin Topological Insulator Bi2Se3 Nanoribbons Exfoliated by Atomic Force Microscopy
Seung Sae Hong, Worasom Kundhikanjana, Judy J. Cha +6
Ultra-thin topological insulator nanostructures, in which coupling between top and bottom surface states takes place, are of great intellectual and practical importance. Due to the…
Few-layer Nanoplates of Bi2Se3 and Bi2Te3 with Highly Tunable Chemical Potential
Desheng Kong, Wenhui Dang, Judy J. Cha +5
Topological insulator (TI) represents an unconventional quantum phase of matter with insulating bulk bandgap and metallic surface states. Recent theoretical calculations and photoe…
Magnetic Doping and Kondo Effect in Bi2Se3 Nanoribbons
Judy J. Cha, James R. Williams, Desheng Kong +6
A simple surface band structure and a large bulk band gap have allowed Bi2Se3 to become a reference material for the newly discovered three-dimensional topological insulators, whic…
Topological Insulator Nanowires and Nanoribbons
Desheng Kong, Jason C. Randel, Hailin Peng +7
Recent theoretical calculations and photoemission spectroscopy measurements on the bulk Bi2Se3 material show that it is a three-dimensional topological insulator possessing conduct…
Aharonov-Bohm interference in topological insulator nanoribbons
Hailin Peng, Keji Lai, Desheng Kong +6
Topological insulators represent novel phases of quantum matter with an insulating bulk gap and gapless edges or surface states. The two-dimensional topological insulator phase was…
