Electron soliton in semiconductor nanostructures
An electron wave packet formed in a semiconductor heterostructure containing a quantum well covered by a metal surface is considered. It is demonstrated that the potential of the charge induced by the electron wave packet on the conducting surface possesses a component of lateral confinement stabilizing its shape. The existence of electron solitons, i.e., running electron wave packets propagati...
متن کاملPicosecond Ultrasonic Microscopy of Semiconductor Nanostructures
We report on a picosecond ultrasonics study of nanostructures by high frequency ultrasound. A sound pulse is generated when an ultra short laser pulse is absorbed in a metal transducer film. The sound propagates across a thin layer (0.5-2 microns) of water and is then reflected from the surface of the sample being examined. The efficiency of optoacoustic detection of the reflected sound is enha...
متن کاملUltrafast Spectroscopy of Wide Bandgap Semiconductor Nanostructures
Group III-nitrides have been considered a promising choice for the realization of optoelectronic devices since 1970. Since the first demonstration of the high-brightness blue lightemitting diodes (LEDs) by Shuji Nakamura and coworkers, the fabrication of highly efficient white LEDs has passed successful developments. A serious physical issue still remained, which prevents their use for high pow...

متن کاملDynamics of electron entanglement in semiconductor nanostructures
Quantum entanglement, the most remarkable feature of quantum physics, is recognized as a resource for quantum information processing. The quest for quantum-computing devices has also produced great interest in entanglement formation in solid-state systems involving quantum effects. Indeed, the functionality of an increasing number of nanodevices is influenced by quantum correlations. In this wo...
