2. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea
Abstract : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. READ MORE

3. Breaking the symmetry : spin splitting of hole subbands in strained quantum wells
Abstract : Properties of the subband structure and related propertiesof quantum wells (QWs) are investigated, within the frameworkof the multi-band envelope function method. The subbands of aQW are replaced by discrete Landau levels when a magnetic fieldis applied perpendicular to the plane of the well. READ MORE

4. MOVPE Growth and Characterization of Low-Dimensional III-V Semiconductor Structures
Abstract : Metalorganic vapour phase epitaxy is used for growth of low-dimensional III-V semiconductor structures. The roughness of heterointerfaces in GaAs/GaInP quantum well structures is studied by photoluminescence emission from extremely narrow quantum wells. READ MORE

5. Epitaxy of GaAs-based long-wavelength vertical cavity lasers
Abstract : Vertical cavity lasers (VCLs) are of great interest aslow-cost, high-performance light sources for fiber-opticcommunication systems. They have a number of advantages overconventional edge-emitting lasers, including low powerconsumption, efficient fiber coupling and wafer scalemanufacturing/testing. READ MORE
