Charged-Particle Interaction Analysis
Online Presentations | 07 Jan 2022 | Contributor(s):: Atilla Ozgur Cakmak, NACK Network
Scanning Electron Microscopy (SEM) has traditionally been the most frequently used micro-/nano- characterization technique to overcome the optical losses coming from lenses. In this talk we are going to begin by discussing the fundamental blocks of an SEM starting from the electron beam emission....

On the Two to Three Dimensional Growth Transition in Strained Silicon Germanium Thin Films
Papers | 02 Feb 2012 | Contributor(s):: Brian Demczyk
Utilizing a model adapted from classical nucleation theory [8], we calculate a "critical thickness" for island formation, taking into account the surfaceenergies of the deposit and the substrate and the elastic modulus of the deposit, to which experimental results for CVD grown silicon germanium...
