Congratulations to ACTAlab postdoc, Dr Xilin Zhou, for winning the best poster award at the Materials Research Society Spring Meeting, which was held in Phoenix USA April 2017. Xilin’s poster discusses the atomic transitions involved in Sb2Te-GeTe superlattices. In particular Xilin showed through a combination of experiments and simulations that the activation energy for disordering of the GeTe layers decreases as more atoms switch, and this leads to an avalanche switching effect.
There were more than 1500 posters presented at the conference, and only 9 were honored with a Best Poster Award. The photograph below shows Xilin with the meeting chairs.
