Evidence of topological edge states in a superconducting nonsymmorphic nodal-line semimetal
L. X. Xu, Y. Y. Y. Xia, S. Liu +18
Topological materials host fascinating low dimensional gapless states at the boundary. As a prominent example, helical topological edge states (TESs) of two-dimensional topological…

Hydride Vapor Phase Epitaxy of GaN on Silicon Covered by Nanostructures
U. Jahn, M. Musolino, J. Lähnemann +8
Several ten m GaN have been deposited on a silicon substrate using a two-step hydride vapor phase epitaxy (HVPE) process. The substrates have been covered by AlN layers and GaN…
