Hot electron injection into dense argon, nitrogen, and hydrogen

Title of thesis : Hot Electron Injection into Uniaxially Strained Silicon

Title of thesis: Hot Electron Injection into Uniaxially Strained Silicon Hyun Soo Kim, Master of Science, 2013 Thesis directed by: Professor Ian Appelbaum Department of Physics In semiconductor spintronics, silicon attracts great attention due to its long electron spin lifetime. Silicon is also one of the most commonly used semiconductor in microelectronics industry. The spin relaxation process...

Raman spectroscopy of hot dense hydrogen.

High P-T Raman measurements of solid and fluid hydrogen to above 1100 K at 70 GPa and to above 650 K in 150 GPa range, conditions previously inaccessible by static compression experiments, provide new insight into the behavior of the material under extreme conditions. The data give a direct measure of the melting curve that extends previous optical investigations by up to a factor of 4 in press...

Phase boundary of hot dense fluid hydrogen

We investigated the phase transformation of hot dense fluid hydrogen using static high-pressure laser-heating experiments in a laser-heated diamond anvil cell. The results show anomalies in the heating efficiency that are likely to be attributed to the phase transition from a diatomic to monoatomic fluid hydrogen (plasma phase transition) in the pressure range between 82 and 106 GPa. This study...
