Strain guides the flow of excitons in 2D materials

Physics World

Using a technique known as strain engineering, researchers in the US and Germany have constructed an “excitonic wire” – a one-dimensional channel through which electron-hole pairs (excitons) can flow in a two-dimensional semiconductor like water through a pipe. The work could aid the development of a new generation of transistor-like devices. In the study, a team led by Vinod Menon at the City College of New York (CCNY) Center for Discovery and Innovation and Alexey Chernikov at the Dresden Univ

Warming Trends: Climate Threats to Bears, Bugs and Bees, Plus a Giant Kite and an ER Surge

Inside Climate News

A column highlighting climate-related studies, innovations, books, cultural events and other developments from the global warming frontier. By Katelyn Weisbrod The Hudson Bay in northern Canada froze up later than normal this year, delaying polar bears’ hunting season by two to three weeks, a nonprofit polar bear conservation organization found. When the ice on the bay is thick enough, polar bears living in the Hudson Bay migrate out onto the ice to hunt for seals.
