Abstract
In both cases, experimental evidence is presented to compliment the predictions made by the theoretical calculations. For monolayer MoS2, experimental Raman measurements confirm a non-uniform redshift of the E2g and A1g modes. In order to confirm the predicted reduction in electron-phonon coupling strength in aluminum, we consider a bulk structure subject to pressure, which allows us to mimic the shorter inter-atomic separation observed in the atomic wires. Experiments confirm a reduction in the electrical resistivity as a function of pressure, due to weakened electron-phonon coupling. These studies suggest new ways of manipulating quantum transport in atomic scale materials.
