ABSTRACTA simple model of thermal dissociation and recovery of hydrogen-passivated silicon defects at the Si/SiO2 interface, such as Pb - centers, during vacuum thermal annealing has been suggested. This model considers reactions of hydrogen with defect states at the Si/SiO2 interface and diffusion of liberated atomic and molecular hydrogen in a silicon dioxide film. An excellent agreement was obtained between the experimental and numerical simulation results for oxides with different thickness (200–1024 Å), grown both (111) and (100) samples and annealed in the temperature range (480–700° C).

AbstractStudies of the thermal dissociation kinetics of Cu-pairs in p-type silicon revealed that the dissociation energy of the pairs is 1.02±0.07 eV, which is twice as large as the binding energy of a coulombically bound donor-acceptor pairs formed by singly charged ions placed on nearest neighbor <111> sites. The dependence of the hole emission rate from the center versus electric field in the depletion region was found to be much weaker than predicted by the Pool-Frenkel law. On the other hand, the polarization potential describing emission from a neutral impurity gave a satisfactory fit to the experimental data. It is concluded that the Cu-pair is a donor with either covalent or mixed type of bonding of interstitial and substitutional copper atoms.

AbstractReverse transcription of the HIV-1 viral RNA genome (vRNA) is an integral step in virus replication. Upon viral entry, HIV-1 reverse transcriptase (RT) initiates from a host tRNALys3 primer bound to the vRNA genome and is the target of key antivirals, such as non-nucleoside reverse transcriptase inhibitors (NNRTIs). Initiation proceeds slowly with discrete pausing events along the vRNA template. Despite prior medium-resolution structural characterization of reverse transcriptase initiation complexes (RTICs), higher-resolution structures of the RTIC are needed to understand the molecular mechanisms that underlie initiation. Here we report cryo-EM structures of the core RTIC, RTIC–nevirapine, and RTIC–efavirenz complexes at 2.8, 3.1, and 2.9 Å, respectively. In combination with biochemical studies, these data suggest a basis for rapid dissociation kinetics of RT from the vRNA–tRNALys3 initiation complex and reveal a specific structural mechanism of nucleic acid conformational stabilization during initiation. Finally, our results show that NNRTIs inhibit the RTIC and exacerbate discrete pausing during early reverse transcription.
