Light-induced transmission nonlinearities in gallium selenide
The intensity of a He–Ne laser ~633 nm, 5 mW! transmitted by different GaSe samples is observed to change in correlation with a Nd-yttrium–aluminum–garnet laser pulse ~532 nm, 7.8 ns, 3 mJ! which excites them. Such time response has been attributed to a nonlinear optical effect, i.e., a decrease in the refractive index due to the exciton screening by the photogenerated carriers. A calculation o...
متن کاملLight-shift-induced photonic nonlinearities
We propose a new method to produce selfand cross-Kerr photonic nonlinearities, using light-induced Stark shifts due to the interaction of a cavity mode with atoms. The proposed experimental set-up is simpler than in previous approaches, while the strength of the nonlinearity obtained with a single atom is the same as in the setting based on electromagnetically induced transparency. Furthermore ...
متن کاملMorphology control of layer-structured gallium selenide nanowires.
Layer-structured group III chalcogenides have highly anisotropic properties and are attractive materials for stable photocathodes and battery electrodes. We report the controlled synthesis and characterization of layer-structured GaSe nanowires via a catalyst-assisted vapor-liquid-solid (VLS) growth mechanism during GaSe powder evaporation. GaSe nanowires consist of Se-Ga-Ga-Se layers stacked t...
متن کاملInvestigation into the crystal structure of gallium-selenide nanowires
Gallium-selenide films grown by heteroepitaxy on silicon substrates exhibit two primary growth structures: layered GaSe and defected zinc-blende Ga2Se3. The latter is seen when growing on the (100) surface of silicon, and an emergent structure of nanowires is observed. My project for the ten week summer program at the University of Washington physics department was to investigate the nanowire s...
متن کاملThree-dimensional frameworks of gallium selenide supertetrahedral clusters.
Dense chalcogenides of Ga, In, and Tl have been extensively studied because of their intriguing stoichiometry and because many of them are semiconductors, photoconductors, or light emitters. On the other hand, while crystalline porous oxides have been known for a long time, the development of crystalline porous chalcogenides, especially selenides and tellurides, is still in its early stages. Co...
