Vapor-liquid-solid growth of highly-mismatched semiconductor nanowires with high-fidelity van der Waals layer stacking
Edy Cardona, Matthew K. Horton, Daniel Paulo-Wach +6
Nanobelts, nanoribbons and other quasi-one-dimensional nanostructures formed from layered, so-called, van der Waals semiconductors have garnered much attention due to their high-pe…
Chemical trends of deep levels in van der Waals semiconductors
Penghong Ci, Xuezeng Tian, Jun Kang +11
Properties of semiconductors are largely defined by crystal imperfections including native defects. Van der Waals (vdW) semiconductors, a newly emerged class of materials, are no e…
Electronic Structure of the Dilute Magnetic Semiconductor from Hard X-ray Photoelectron Spectroscopy and Hard X-ray Angle-Resolved Photoemission
Armela Keqi, Mathias Gehlmann, Giuseppina Conti +18
We have investigated the electronic structure of the dilute magnetic semiconductor (DMS) and compared it to that of an undoped reference sample, using h…
Carrier Lifetimes in a III-V-N Intermediate Band Semiconductor
J. N. Heyman, A. M. Schwartzberg, K. M. Yu +5
We have used transient absorption spectroscopy to measure carrier lifetimes in the multiband band semiconductor GaPAsN. These measurements probe the electron populations in the con…
On the rotational alignment of graphene domains grown on Ge(110) and Ge(111)
P. C. Rogge, M. E. Foster, J. M. Wofford +3
We have used low-energy electron diffraction and microscopy to compare the growth of graphene on hydrogen-free Ge(111) and Ge(110) from an atomic carbon flux. Growth on Ge(110) lea…
Real-time observation of epitaxial graphene domain reorientation
Paul C. Rogge, Konrad Thürmer, Michael E. Foster +3
Graphene films grown by vapor deposition tend to be polycrystalline due to the nucleation and growth of islands with different in-plane orientations. Here, using low-energy electro…
