ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Hot-filament chemical vapor deposition is a common method employed for diamond deposition. Due to the filament-substrate proximity, large temperature variations across the substrate is often possible. Variations in substrate temperature need to be minimized in order to deposit polycrystalline diamond films of uniform thickness over large areas. Thus heat transfer calculations which consider radiation from the filament to the substrate, radiation from the substrate to the reactor walls, and finally conduction in the silicon wafer have been developed to predict substrate temperature profiles as a function of the filament shape and geometry. The calculated values are found to be in reasonable agreement with experimentally measured substrate temperatures. It was found that hydrogen atom recombination makes a significant contribution to the absolute substrate temperature, but that the normalized temperature profiles are determined primarily by the radiation flux distribution. The effects of the other deposition parameters are also discussed. Comparison with experimental results show an apparent correlation between growth rate profiles and radiation flux profiles from the filament as predicted by the calculations.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Impurity-induced disordering of III-V compound semiconductor quantum well heterostructures and superlattices has been extensively studied. However, the theories proposed to explain this phenomenon have dealt primarily with vacancy diffusion mechanisms and have not succeeded in explaining all the experimental observations satisfactorily. In this communication, we propose a two-atom ring mechanism of diffusion based on a simplified model of covalent bonding in III-V compound semiconductors and suggest that the phenomenon of intermixing is a consequence of a lowering in the activation energy due to coulombic interactions between the substitutional impurity atoms and the host atoms. This mechanism is consistent with experimental observations and is able to predict the behavior of other dopants. The additive effect of the simultaneous presence of different dopants can also be explained by this theory which could possibly be used to achieve controlled layer disordering for use in device technology.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Contrary to recent predictions, it has been observed that the addition of small quantities of hydrogen, ethanol, and benzene to nitrogen reduce the output power of a nitrogen laser. N,N-dimethylaniline enhances the output power of the laser by 25%. A Penning ionization process is proposed as a mechanism for quenching the B 3Πg state of nitrogen.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Collisional interruption of coherent excitation of SF6 in the lower discrete region of its laser absorbing mode (ν3) have been studied using the recently developed quantum Monte Carlo wave function (QMCWF) method. The usual pure pump mode description up to 3ν3 and complete mixing of all modes (QC) above it have been assumed. The rotational and anharmonic splitting of the vibrational states upto 3ν3 are taken into account but splitting due to tensor interaction terms are neglected. Excitation to QC is represented by irreversible leakage from the coherent ladder modeled by an imaginary term in the Hamiltonian of the coherently excited vibrational rotational levels. QMCWF study has been carried out at the laser frequency 942.8 cm−1 for which the local time average populations in the intermediate excited vibrational states are found to be negligible. Large leakage occurs only from narrow band of ground rotational states due to 3 photon resonances but their number increases with increasing intensity. Two different collisional energy transfer models, one obeying symmetry imposed restrictions and propensity rule, and the other free from such restrictions except the fact that collisions restore the thermal distribution, have been used. Results show different pressure effects at different temperature and for different intensities. However, the two different models used for collisional rotational transition probabilities give similar enhancement of leakage at high intensities. © 1994 American Institute of Physics.Type of Medium: Electronic ResourceURL: -
