Temperature-Dependent X-ray Diffraction Measurements of Infrared Superlattices Grown by MBE

Crystals, 2016
Strained-layer superlattices (SLSs) are an active research topic in the molecular beam epitaxy (MBE) and infrared focal plane array communities. These structures undergo a >500 K temperature change between deposition and operation.

Massive Dirac surface states in topological insulator/magnetic insulator heterostructures

, 2012
Topological insulators are new states of matter with a bulk gap and robust gapless surface states protected by time-reversal symmetry. When time-reversal symmetry is broken, the surface states are gapped, which induces a topological response of the ...
