Direct observation of electron emission as a result of a VVV Auger transition in the valence band of Graphene
V. A. Chirayath, V. Callewaert, M. D. Chrysler +11
We report the first direct observation of electron emission into the vacuum as a result of a VVV Auger transition resulting from the relaxation of a deep hole in the valence band.…
Positron surface state as a spectroscopic probe for characterizing surfaces of topological insulator materials
Vincent Callewaert, K. Shastry, Rolando Saniz +8
Topological insulators are attracting considerable interest due to their potential for technological applications and as platforms for exploring wide-ranging fundamental science qu…
3D Dirac cone carrier dynamics in Na3Bi and Cd3As2
G. S. Jenkins, C. Lane, B. Barbiellini +12
Optical measurements and band structure calculations are reported on 3D Dirac materials. The electronic properties associated with the Dirac cone are identified in the reflectivity…
