Our research focuses on the understanding and controlling the properties of semiconductor nanostructures. We are especially interested in epitaxial growth of III-V nanowires by MOVPE and characterization of their structural and composition by TEM. Our main interest today is in combining these two methods in order to study and understand nanowire growth using in-situ TEM.
Specific research projects:
Fundamental studies of crystal growth by in-situ TEM
We are interested in investigating and understanding the basic processes that occur during nucleation and growth of semiconductor crystals, including nanowires. This research is conducted using a custom hybrid CVD-TEM, where III-V semiconductor growth is conducted inside a TEM with real-time imaging and analysis.

Atomic scale ordering for exotic electronic phases
In this new project we are aiming to use precise control of crystal phase in nanowires to develop crystal phase heterostructures, which will be used to explore exotic electronic and excitonic effects. Our efforts in this area involve developing novel structures using MOCVD, as well as theoretical modeling of nanowire growth to understand the factors determining crystal structure.
