Characterization of quantum well structures using surface photovoltage spectroscopy

In this work a novel method to characterize quantum well (QW) structures and devices is presented. The method is based on the well-known surface photovoltage spectroscopy (SPS) and on numerical simulations. It is shown that the surface photovoltage is sensitive to the electron hole energy transition levels in the well layer as well as to features of other regions of the structure. The photovolt...

Pulsed ESR dipolar spectroscopy for distance measurements in immobilized spin labeled proteins in liquid solution.

Pulsed electron spin resonance (ESR) dipolar spectroscopy (PDS) in combination with site-directed spin labeling is unique in providing nanometer-range distances and distributions in biological systems. To date, most of the pulsed ESR techniques require frozen solutions at cryogenic temperatures to reduce the rapid electron spin relaxation rate and to prevent averaging of electron-electron dipol...

Observation of an inverse Doppler shift from left-handed dipolar spin waves

We report the experimental observation of an inverse Doppler shift from the motion of an ordinary solid object. The experiment used left-handed, or backward, spin waves in a magnetic thin film. As a pick-up antenna was moved toward the spin wave source, the measured frequency decreased. In contrast, an increase would be expected in everyday experience as the observer approaches the source. The ...

Spin correlation in kagomé ice state : neutron scattering study of the dipolar spin ice Dy 2 Ti 2 O 7 under magnetic field along [ 111 ]

Spin correlation in kagomé ice state: neutron scattering study of the dipolar spin ice Dy 2 Ti 2 O 7 under magnetic field along [111] Abstract We have investigated the kagomé ice state in the frustrated pyrochlore oxide Dy 2 Ti 2 O 7 under magnetic field along a [111] axis. Spin correlations have been measured by neutron scattering and analyzed by Monte-Carlo simulation. The kagomé ice state, w...
