ADVANCES IN SEMICONDUCTOR-MATERIALS AND STRUCTURES FOR OPTICAL SENSORS APPLICATIONS

Optical sensors applications involve both detection and emission systems. For semiconductor-based devices, sensor applications naturally exploit any improvement in materials technology that improves or extends optical functions. In this paper, recent developments in the growth of semiconductor materials, structures, and devices are discussed, especially low-dimensional systems. Novel materials systems, which are essential 'self organising systems', may be important in future technologies including optical device functions. One such system is porous Si, and some properties of this material are briefly reviewed.
