Calculating characteristic timescales for environmental decoherence in the presence of thermal gravitons

Creator:

Nelson, Hunter

Abstract:

Different models show the effects of environmental decoherence on a quantum system due to various environments of interest. One important quantity within these models is the decoherence time, which tells us how quickly environments wash away the coherence of local measurements. We can describe this effect as the quantum system...

Repair of a Scanning Tunneling Microscope and Retesting for the Formation of Pyramidal Structures Formed on Sputtered Germanium (110)

Creator:

Betz, Hazel R.

Abstract:

Semiconducting materials are of immense importance due to their presence in almost all modern devices. It is possible that the surface physics of semiconductors could be used to control the nanoscale topography and properties of these materials, ultimately creating new options for device fabrication. This could result in profound implications...

Spectroscopic Ellipsometry on Thin Films of TiO2: Comparing Cauchy and Cody-Loretnz Models in CompleteEASE

Creator:

Kreb, Joseph

Abstract:

Spectroscopic ellipsometry (SE) is used to characterize amorphous and crystalline thin films of TiO2. Amorphous precursor films of TiO2 are deposited by radio frequency magnetron sputtering on fused silica and silicon substrates. Annealing the amorphous precursor films induces them to crystallize into either pure or mixed phases of the three...
