SPIN OSCILLATIONS IN STORAGE RINGS [PDF]
Spin 2004, 2005 The dependence of the particle rotation frequency on the particle orbit perturbations is found. The exact equation of spin motion in the cylindrical coordinate system is derived. The calculated formula for the frequency of g-2 precession is in the best agreement with previous results.

Low-Voltage High-Speed Ring Oscillator With a-InGaZnO TFTs
IEEE Journal of the Electron Devices Society, 2020 This paper presents a high-speed ring oscillator (RO) with amorphous Indium-Gallium-Zinc-Oxide Thin-film transistors (a-IGZO TFTs). The proposed RO reduces the delay of a single stage inverter using intermediate signals generated within the RO, hence ...

Alternate oscillations in semiconductor ring lasers [PDF]
Optics Letters, 2002 We report on fabrication and characterization of single-longitudinal- and transverse-mode semiconductor ring lasers. A bifurcation from bidirectional stable operation to a regime with alternate oscillations of the counterpropagating modes was observed experimentally and is theoretically explained through a two-mode model. Analytical expressions for the

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.
