Local Vibrational Mode Spectroscopy of Hydrogen in Compound Semiconductors
Infrared (IR) and Raman spectroscopy are useful techniques for characterizing hydrogen-related defects in semiconductors. This paper will focus on hydrogen in compound semiconductors such as AlSb, GaAs, GaN, InP, and ZnO. In most compound semiconductors studied to date, hydrogen forms neutral complexes with donors or acceptors. In GaN:Mg grown by metalorganic chemical vapor deposition, for exam...
متن کاملCC-CCTA-Based Current-mode Quadrature Oscillator
This article presents a current-mode quadrature oscillator using current controlled current conveyor transconductance amplifiers (CC-CCTAs) as active elements. The proposed circuit is realized from a lossy integrator and a lossy differentiator. The oscillation condition and oscillation frequency can be electronically controlled via input bias currents. The proposed oscillator can be applied to ...
متن کاملPerturbation theory approach to dynamical tunneling splitting of local mode vibrational states in ABA molecules
We introduce a point of view for treating the dynamical tunneling splitting of symmetric local mode vibrational states in ABA molecules (A = H typically) which is the one we have employed in treating the vibrational spectroscopy of CH overtones in molecules such as (CXs),YCCH. Namely, the vibrational coupling corresponding to the dynamical tunneling in semiclassical mechanics via many intermedi...
متن کاملAssigning the transition from normal to local vibrational mode in SO by periodic orbits
The bifurcation diagrams of periodic orbits are compared for three different potential functions of the ground electronic state of SO . By assigning families of periodic orbits to overtone and combination vibrational levels of the symmetric stretch 2 mode, the transition from normalto local-type motions is identified to take place at the energy where the symmetric stretch family turns from stab...
متن کاملBreaking atomic bonds through vibrational mode localization
We apply the lattice instability analysis to homogeneously strained single crystal with a flat or defected surface to demonstrate that, in the process of emission of dislocation by an unstable surface, prior to the breaking of atomic bonds, a vibrational mode localizes, foretelling the location and the manner of the impending microscopic catastrophic event.
