摘要:

The value of the electronic conductivity of polymers such as polyacetylene, polypyrrole and polythiophene can be varied over many orders of magnitude, from semiconducting to metallic, by chemical doping. Charge carriers in these materials have interesting properties which are currently the subject of extensive investigation. Much of the experimental interest is stimulated by possible practical applications.

摘要:

Over the past fiie years the use of diode lasers in physics research has expanded rapidly. In part, this has occurred because the diode laser is a highly monochromatic and tunable light source that, when compared to other laser systems, is quite inexpensive and easy to operate. These characteristics make the diode laser ideal for multi-laser experiments, or small scale/high quality research projects in general. In this article a brief introduction to the AlGaAs single-mode diode laser's characteristics and operation is presented, along with an overview of this laser's contributions to atomic physics research to date. It is hoped that this review will facilitate the further use of diode lasers in all aspects of physics, and in particular will aid the small scale researcher in attaining a more active place in mainstream physics.

摘要:

An overview is presented of the emerging area of optical storage of information, placing emphasis on alkali halide crystals as the prototype storage media. The twin phenomenon of photochromism and photodichroism exhibited by colour-centred alkali halides can be exploited for purposes of information storage. In such storage media picture information can be stored by direct as well as holographic methods and the Hurter-Driffield (H-D) characteristics can be established. It is shown that alkali halides are a useful material for fundamental research on optical storage of information.
