Silicene's Suicidal Tendencies Can Be Overcome

Silicene's Suicidal Tendencies Can Be Overcome

Early this year, research indicated that silicene—essentially two-dimensional (2-D) silicon —had “suicidal tendencies”. As soon as you tried to layer silicene it would revert back to the crystal structure of silicon instead of maintaining its honeycomb structure. Now an international team of researchers claims to have proven the stability of silicene under these circumstances, paving the way for it to compete in the growing world of 2-D materials . The research, which was published in the journal 2D Materials , demonstrated for the first time that thick, multilayer silicene films can be stable in air for at least 24 hours. While 24 hours doesn’t seem like a long time, it should give researchers a window of opportunity to perform more tests on the material to reveal its capabilities. The joint Italian and French research team was able to slow the reversion of silicene back ...
