Gas Phase Diagnostics Of Cvd Diamond Growth From Chloromethane And Chloroform, James M. Chenault
Gas Phase Diagnostics Of Cvd Diamond Growth From Chloromethane And Chloroform, James M. Chenault
Masters Theses
Low energy electron impact ionization (LEEII) time of flight mass spectrometry (TOFMS) has been used to interrogate gases sampled through an orifice from a diamond growth surface. Methane, chloromethane and chloroform precursor gases were examined to produce electron energy plots of the fragment ions that occur using LEEII. Filament temperature studies were completed covering temperatures from room temperature to over 2000 °C, and the results were compared to the LEEII plots. The monochloromethyl radical has been detected in the experiments using chloroform and the effect of a pretreatment with this radical present has been shown to enhance diamond nucleation. …

In East Tennessee, the Tennessee River and its tributaries cut across many of the sub-parallel strike valleys in the Valley and Ridge several times, including the karstic carbonate strike belts within them. The construction of dams along the Tennessee River and its tributaries, including the Clinch River, has increased the river stage between 5 and 20 m, which caused inundation of considerable areas. This also raised the baselevel for drainage, thus altering the groundwater regime within the valleys intersected by these rivers. The stud area addressed in this research includes an industrial facility situated on karstic carbonate bedrock which is …
