Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Nanolithography on H:Si(100)-(2 x 1) using combined Scanning Tunneling Microscopy and Field Ion Microscopy techniques
DownloadFall 2011
This thesis reports on the combined techniques of ultra-high vacuum scanning tunneling microscopy (UHV-STM) and field ion microscopy (FIM). The apex structure of STM scanning tips correlates with their ability to yield highly-resolved images and to perform accurate hydrogen desorption on...

Protein folding involves a stochastic search through the configurational energy landscape towards the native structure. Although most proteins have evolved to fold efficiently into a unique native structure, misfolding (the formation of non-native structures) occurs frequently in vivo causing a...

The formation of an abnormal form of proteins in cells can cause aggregation and neurodegenerative pathology, such as Alzheimer’s, Parkinson’s and prion diseases, which affects both humans and animals. Nowadays, the understanding of the mechanism of prion misfolding and propagation, including...
