Transition metal dichalcogenide (TMDC) materials are very important inelectronic and optical integrated circuits and their growth is of great importance in thisfield. In this paper we present growth and fabrication of MoS2 (Molibdan DiSulfide)thin films by chemical bath method (CBD). The CBD method of growth makes itpossible to simply grow large area scale of the thin la...

Photoluminescence and positron annihilation spectroscopy have been used to characterize and identify vacancy-type defects produced in ZnO films grown on sapphire by metal-organic chemical-vapor deposition. The photoluminescence of the samples in the near band edge region has been studied, paying particular attention to the emission at 370.5 nm 3.346 eV . This emission has been correlated to the...

Cadmium sulphide (CdS) thin films were deposited onto glass substrates by chemical bath deposition (CBD) from a bath containing cadmium acetate, ammonium acetate, thiourea and ammonium hydroxide. The CdS films were annealed in air at various temperatures (350, 400 and 450 °C) for 60 minutes, and times (5, 15, 30, 45 and 60 minutes) at constant temperature (400 °C) in order to investigate the in...

Affluent neighborhoods present a potentially attractive location for retail establishments because of their higher purchasing power and demand for a wide range of specialized goods and services. However, if high income households perceive retail in general – or certain types of retail, such as Big Box stores – as an undesirable use, they may be able to block commercial development through zonin...

Genetic conservation and improvement depends (among other things) on the action of local people (CBD, 1994). We know that farmers are extremely knowledgeable about their crops and that they continuously experiment with them and with new materials arriving from various sources (Richards, 1989). Certain farmers are locally recognised as having “expert” knowledge about agro-biodiversity. They are ...

Component-based development i s a n emerging discipline of software development. Recently, the growth of middleware technologies brings the notion of serverside component into CBD f o r developing missioncritical applications. In this paper, we propose the method f o r designing reliable component systems for mission-critical tasks. To this end, we formulate the MTS system and develop the frame...
