Dipole scattering in polarization induced two-dimensional electron gases
Unusually large spontaneous and piezoelectric fields in the III-V nitrides have led to the making of an entirely new class of two-dimensional electron gas. Fluctuation from a perfectly periodic binary structure in highly polar semiconductor alloys present the same physical situation as a random distribution of microscopic dipoles. The excess dipole distribution in the barrier layers is evaluate...
متن کاملMany-body dipole-induced dipole model for electrorheological fluids
Theoretical investigations on electrorheological (ER) fluids usually rely on computer simulations. An initial approach for these studies would be the point-dipole (PD) approximation, which is known to err considerably when the particles approach and finally touch due to many-body and multipolar interactions. Thus various work attempted to go beyond the PD model. Being beyond the PD model, previ...
متن کاملPolarization sensitivity of optical resonant dipole antennas
The polarization sensitivity of optical resonant dipole antennas is investigated numerically using the Green’s tensor technique. The electric field-intensity in the feed-gap of the antenna is calculated as function of the polarization of the incident field. A simple analytical model is proposed that matches the numerical data very well. While a very strong polarization sensitivity can be achiev...
متن کاملEffect of Induced Dipole-Induced Dipole Potential and the Size of Colliding Particles on Ion-Quadrupolar Molecule Collision Rate Constants
Classical trajectory (Monte Carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the H¯+C2H2 system. The method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. It is also assumed that the colliding particles have a d...
متن کاملIntermolecular Dipole-Dipole Relaxation of lz9Xe Dissolved in Water: Implications for Spin Polarization-Induced NOE in the Lungs
Introduction Hyperpolarized gas MRI has been shown capable of generating high-resolution images of air spaces. Although useful, these images carry only indirect information about the lung parenchyma itself. Spin polarization-induced nulcear Uverhauser effect (SPINOE) has been successfully used to create proton enhancements in few molecules that interact with xenon (1). Intriguing is therefore t...
