Controlling charge doping in 2D materials

by | Feb 7, 2022 | Balgley, Jesse, Henriksen, Erik

— Technology Description

Researchers at Washington University in St. Louis have developed a method to control charge doping in 2D materials like graphene. This method uses α-RuCl3 to create pn junctions at a smaller scale than silicon transistors.

While α-RuCl3 efficiently removes el…

Compressed-sensing Ultrafast Photography (CUP)

by | Mar 10, 2018 | Gao, Liang, Liang, Jinyang, Wang, Lihong

— Compressed-sensing ultrafast photography (CUP) is an ultrafast imaging technique that can capture non-repetitive, time-evolving events at up to 100 billion frames per second. Compared to existing ultrafast imaging methods, CUP has a prominent advantage in measuring an x, y, t (x, y, spatial coordina…
