Electrons, Holes, and Spin in Monolayer Four-Six-enes

A study by CNAM members Prof. Ian Appelbaum and Dr. Pengke Li has been featured as an Editor's Suggestion in PRB. Applying group theoretic methods to study the unusual electronic structure of atomically-thin two-dimensional "four-six-ene" semiconductors such as tin sulfide, germanium telluride, etc, this work provides a straightforward framework for understanding the consequences of inversion symmetry breaking due to inequivalent sublattice atomic identity. In particular, the quantum states at the edge of the fundamental bandgap -- relevant to all transport, optoelectronic, and spintronic properties -- are shown to directly inherit their character from nearby points of high symmetry in the reciprocal lattice, where the form of allowable energetic interactions is constrained. This work is published in Physical Review B; more information can be found on Prof. Appelbaum's web site.

Nick Butch Awarded Katharine B. Gebbie Young Investigator Award

CNAM Affiliate member Prof. Nick Butch was awarded the 2016 Katharine B. Gebbie Young Investigator Award by the NIST chapter of Sigma Xi for his contributions to the study of unconventional superconductors, topological insulators, and other quantum matter. He will be presenting a lecture on "The Allure of Hidden Order" at NIST on Friday, October 21 (see details here). For more information on Prof. Butch's research see this link.

Appelbaum Elected APS Fellow

Prof. Ian Appelbaum has been elected as a Fellow of the American Physical Society “for advancing the study of spin-polarized electron transport in semiconductors, especially the fundamental processes revealed by coherent and time-resolved spin transport over macroscopic distances in silicon and germanium.” APS Fellowship is a distinct honor signifying recognition by professional peers, and its membership includes a long list of prestigious and accomplished physicists -- congratulations Ian!! More information about Prof. Appelbaum's research can be found on his research page.

 

CNAM and JQI Members on Team Awarded $33M Australian Prize

The Australian Research Council (ARC) has just announced $283.5M in funding for nine ARC Centres of Excellence, including the ARC Centre of Excellence in Future Low Energy Electronics Technologies. The team, which includes Prof. Johnpierre Paglione of CNAM and Profs. Victor Galitski, William Phillips and Dr. Ian Spielman of the Joint Quantum Institute, will be led by former CNAM Director Michael Fuhrer and established at Monash University in Melbourne, Australia. The Centre will develop the scientific foundation and intellectual property for new electronics technologies to decrease energy consumption by realising fundamentally new types of electronic conduction. More information can be found in the media release.
