Abstract
As computing power has advanced over the last 20 years, we have been able to use molecular dynamics computer simulations to better understand the phase transitions exhibited by various molecules adsorbed onto surfaces. In particular, great advances have been made in understanding the nematic and smectic crystal phases that exist in between solid and liquid phases of organic layers. The means of characterizing these fascinating phases of matter and the mechanisms that drive associated phase transitions will be discussed, followed by extensions to current work on more complex organic layers. Finally, the current trajectory of large scale computing along with a computational wish list will be discussed. Throughout the talk there will be anecdotes from our research group that will give context to various elements of the work presented here.
