Summary: The thermal conductivity of amorphous solids can be increased through ion irradiation, altering the bonding network configuration. Films with higher initial hydrogen content show the greatest enhancement, accompanied by stiffening and densification from the irradiation process. This enhancement in vibrational transport is unique compared to the structural degradation and reduced thermal conductivity typically seen in ion conductivities of crystalline materials.

Summary: The study investigates the effects of silicon isotopic abundance on EDMR and NZFMR effects observed on unpassivated Si/SiO2 metal-insulator-semiconductor capacitors. The results show a significant narrowing of the NZFMR response upon removal of Si-29 nuclei, with superhyperfine interactions playing a crucial role in determining the response breadth. It is strongly suggested that leakage currents involve tunneling from Si/SiO2 P-b dangling bonds to defects within the oxide, indicating a dominant role of Si/SiO2 interface trap defects in the observed phenomena.

Summary: This study investigates the low-frequency EDMR and NZFMR responses observed on unpassivated Si-28/(SiO2)-Si-28 MIS capacitors, demonstrating the connection between the spin-mixing mechanism and NZFMR response. By fitting the spectra, a dipolar coupling constant can be extracted, suggesting magnetic dipolar interactions between P-b centers at the interface are responsible for the NZFMR response in the absence of electron-nuclear hyperfine interactions.

Summary: Carborane (C2B10H12) molecules are unique precursors for self-assembled monolayer (SAM) applications. These 3D, icosahedral (12-vertex) molecules allow for well-ordered layers formation with fewer defects compared to traditional linear alkyl SAMs. Post-growth treatments like heat and plasma can be used to crosslink and stabilize the films. These carborane thiol SAMs show stability to thermal and plasma treatment, with some changes in boron coverage and oxidation. The films can be further stabilized and modified by plasma treatment and may have various applications in functional and protective layers.
