Various Quantum- and Nano-Structures by III–V Droplet Epitaxy on GaAs Substrates
We report on various self-assembled In(Ga)As nanostructures by droplet epitaxy on GaAs substrates using molecular beam epitaxy. Depending on the growth condition and index of surfaces, various nanostructures can be fabricated: quantum dots (QDs), ring-like and holed-triangular nanostructures. At near room temperatures, by limiting surface diffusion of adatoms, the size of In droplets suitable f...
متن کاملMagnetotransport in an aluminum thin film on a GaAs substrate grown by molecular beam epitaxy
Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temp...
متن کاملTwo Droplets interaction on substrate
Dynamics of two droplets interactions on a substrate (droplet impact on a sessile droplet) are numerically investigated using OpenFOAM. The impact speed, location of the impacting droplet, viscosity and surface tension were varied in the numerical studies. We found that when the surface tension dominates the flow, the mass canter of two droplets moves to impacting droplet side. When the inertia...
متن کاملA Transmission Electron Microscopy Study on Self-Catalyzed GaAs Nanostructures
Semiconductor nanostructures are potential building blocks for many applications in photonics, electronics, physics, and life sciences. They are also a good candidate to study quantum mechanics and related novel phenomena, based on the dimensionality and the size reduction. Among various nanostructures, one-dimensional (1-D) III-V nanostructures grown on Si substrates have received a lot of att...
متن کاملFormation of highly ordered nanostructures by drying micrometer colloidal droplets.
Nanoparticles with well-defined chemical compositions can act as building blocks for the construction of functional structures, such as highly ordered aggregates, as well as porous and hollow aggregates. In this work, a spray-drying technique is used to form a crystal-like structure with nanoparticle building blocks. When spray-drying uniform spherical particles, tightly packed aggregates with ...
