Physics and Technology of Elemental, Alloy and Compound Semiconductor Nanocrystals: Materials and Devices (SEMINANO) - Publishable Final Activity Report

Project ID: 505285
Funded under: FP6-NMP

Abstract

The primary objective of this project was to develop fundamental knowledge on the production techniques, characterization and methods of applications of semiconductor nanocrystals to light emitting devices and floating gate memories. Three main research directions can be identified in the SEMINANO project : First, physics and chemistry of a number of elemental, alloy and compound semiconductor nanocrystal formation and mechanisms of charge tranport and light emission was studied in a systematic way to acquire fundamental knowledge. Second, methods and technology of obtaining new materials with well characterized nanocrystals suitable for use in device work was developed. Finally, devices such as Metal Oxide Semiconductor (MOS) structures for use in flash memories and light emitting devices (LEDs) has been designed, fabricated and tested with the unique features of nanocrystals. Full cycle starting from material processing to the demonstration of devices was covered. Different materials, production techniques, processing conditions and characterization techniques were employed to reach comprehensive results for the science and technology of semiconductor nanocrystals. As its main objectives are strongly related to the size dependent phenomena in semiconductors and its outcomes has formes the basis for the new production techniques in the modern microelectronic and photonic industry.
