Infrared avalanche photodiodes from bulk to 2D materials

Avalanche photodiodes (APDs) have drawn interest in recent years and extensively used in many applications to include the most important – optical communication. Unquestionably optical quantum information applications such as quantum key distribution also drive that trend putting severe requirements on detector performance. Towards this goal the authors showed the evolution and the recent development of AIIIBV, AIIBVI and potential alternative – “third wave” superlattices and 2D materials APDs.

All together now: Experiments with twisted 2D materials catch electrons behaving collectively

A team led by the University of Washington reports that carefully constructed stacks of graphene — a 2D form of carbon — can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.

Scientists Dive Deep Into Hidden World of Quantum States

A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore’s Law.
