PhD defense of Francis Chen-Chi Chien, June 2018
Talk in Cavtat 2016 “2D materials nanosculpting & bio-applications”, artistic representation by Nathaniel Miller.

Research in our lab is based on physics and is focused on the exploration of nanoscale and mesoscopic structures with the emphasis on nano electronics, transmission electron microscopy and science of nanoscale & atomic scale systems. The systems that we study include nanoparticles, nanowires, 2D materials and others. For more details, please scroll through our publications. We are experts in transmission electron microscopy, specifically using in situ TEM methods to correlate structure of materials & devices to their properties & function, materials’ synthesis and characterization, low-noise and variable-temperature electrical measurements, fluorescence microscopy, atomic and electric force microscopy, biomolecule measurements with nanopores and so on. We developed the first graphene nanopores for DNA analysis in 2010 as well as  new in situ TEM techniques for probing and studying materials at the single atom scale in the recent years. The first transistor measurement inside of the TEM  was performed by Dr. Rodriguez-Manzo by carving a graphene sheet into a transistor in situ in the TEM and performing a three-terminal measurement.

We continue to push the frontiers of devices and materials’ applications including the understanding of novel 2D materials, transistors and nanowires, DNA & protein sequencing devices, and the understanding of new electronic phenomena towards quantum information processing. We develop materials and procedures enabling technologies and expanding horizons of physics, chemistry, materials science and nanotechnology. Labs are in David Rittenhouse Laboratory (DRL), the Singh Center for Nanotechnology (Singh Center) and the Laboratory of Research of Structure of Matter (LRSM).

We are seeking motivated graduate students & postdoc to join our effort on the advancement of fundamental nanoscale science, including nanoscale and quantum devices from 2D and other materials,  nanopores, 2D materials development, advanced electron microscopy and so on.
