Scanning tunneling microscopy and spectroscopy of graphene on semiconducting surfaces
… to better understand the perturbation of the physical and electronic structure of graphene monolayers and bilayers due to interactions with the supporting substrate, we have utilized scanning tunneling microscopy (STM) and spectroscopy (STS) to probe the graphene-substrate interaction for …

Molecular manipulation with the scanning tunnelling microscope
This thesis presents two studies into molecular manipulation using scanning tunnelling microscopy (STM), dissociation of chrolobenzene (PhCl) and of 4,4´ dichlorobiphenyl (PCB) manipulation both on Si(111)-7×7 surface. An ab initio investigation is presented on a possible candidate for future …

X-ray studies of metal thin film growth on semiconductors
Real time in situ synchrotron x-ray studies of continuous Pb deposition on Si(111)-(7 × 7) at 180 K reveal an unusual growth behavior. A wetting layer forms first to cover the entire surface. Then islands of a fairly uniform height of about five monolayers form on top of the wetting layer and grow …

Atomic-scale assessment of graphene-substrate interactions, grain boundaries, and materials for heterostructures
… defects from wafer-scale graphene synthesis, graphene-substrate interactions, and growth of graphene’s insulating analog, hexagonal boron nitride (h-BN). These experimental studies are fundamental in nature, but they highlight parameters relevant to applications. Chemical vapor deposition …

Angle-resolved photoemission and first-principles studies of topological thin films
… electronics and quantum computation. In this thesis research, the combination of angle-resolved photoemission spectroscopy (ARPES) and first principles calculation is used to examine the electronic properties of topological thin films and 2D electronic systems with large spin-orbit splitting. The …
