Background
Molecular Beam Epitaxy (MBE) is a technique used to create very thin layers of a single crystal on a substrate. This is crucial in the semiconductor industry to develop devices like transistors, which are essential for electronics. In MBE, researchers focus on how layers are formed atom by atom, allowing for highly precise and controlled growth. Kinetic Monte Carlo (KMC) simulations are used as a tool to predict and analyze how these crystals form under different conditions by using random selection processes.
History
Molecular Beam Epitaxy was developed over the past few decades and has been pivotal in advancing semiconductor technology. Initially, it was primarily used for research, but its applications have expanded due to its ability to form extremely precise structures, leading to the development of more efficient electronic devices. The use of Kinetic Monte Carlo simulations is a more recent advancement that allows scientists to better understand and control crystal growth processes.
