Multiple Cracks Propagate Simultaneously in Polymer Liquids in Tension

Qian Huang, Nicolas J. Alvarez, Aamir Shabbir, and Ole Hassager

Phys. Rev. Lett. 117, 087801 (2016) - Published 15 August, 2016

EDITORS' SUGGESTION

Strain Engineering of the Band Gap of HgTe Quantum Wells Using Superlattice Virtual Substrates

Philipp Leubner, Lukas Lunczer, Christoph Brüne, Hartmut Buhmann, and Laurens W. Molenkamp

Phys. Rev. Lett. 117, 086403 (2016) - Published 19 August, 2016

The band gap of HgTe quantum wells can be controlled by adjusting their strain via a substrate lattice mismatch. The achieved band gap of 55 meV is well above room temperature thermal energy, which may allow for technical applications of these 2D topological insulators.
