Electronic structure of solid nitromethane:Effects of high pressure and molecular vacancies
Electronic structure solid nitromethane high pressure and molecular vacancies
2015/10/16
The combined effect of pressure and molecular vacancies on the atomic structure and electronic properties of solid nitromethane, a prototypical energetic material, is studied at zero temperature.The s...

2015/10/16
Below the roughening transition, crystal surfaces have macroscopic plateaus, facets, whose evolution is driven by the microscale dynamics of steps. A long-standing puzzle was how to reconcile discrete...
