Effect of Post Thermal Annealing on the Optical Properties of InP/ZnS Quantum Dot Films
The enhancement of optical properties via thermal annealing on InP/ZnS core/shell quantum dot (QD) film was investigated in this work. The increase of emission intensities of the QD films was observed after thermal annealing at 180 °C for 5 min.

Twisted-light-induced intersubband transitions in quantum wells at normal incidence [PDF]
We examine theoretically the intersubband transitions induced by laser beams of light with orbital angular momentum (twisted light) in semiconductor quantum wells at normal incidence. These transitions become possible in the absence of gratings thanks to

Semiconductor-based Geometrical Quantum Gates [PDF]
We propose an implementation scheme for holonomic, i.e., geometrical, quantum information processing based on semiconductor nanostructures. Our quantum hardware consists of coupled semiconductor macroatoms addressed/controlled by ultrafast multicolor ...

Hot Carrier Photocurrent through MOS Structure
Flow of photocurrent through the metal-oxide-semiconductor structure induced by the pulsed infrared CO2 laser is investigated experimentally. In the case of a perfect insulator, the photocurrent has a photocapacitive character.

Intensity noise reduction in semiconductor lasers by amplitude-phase decorrelation [PDF]
Detuned operation of a laser results in coupling of field amplitude and phase fluctuations. In a semiconductor laser, this coupling is known to be very large.

Improved Optical Property and Lasing of ZnO Nanowires by Ar Plasma Treatment
ZnO nanowires play a very important role in optoelectronic devices due to the wide bandgap and high exciton binding energy. However, for one-dimensional nanowire, due to the large surface to volume ratio, surface traps and surface adsorbed species acts ...
