Photonic, electronic, and acoustic properties of quantum-sized silicon have been studied for their characterizations and device applications toward the functional integration. The results and significances are summarized as follows.(1) Development of photonic devices based on enhanced luminescence- It was confirmed by combination of anneal with surface passivation that both the efficiency and the stability were much improved, and then the evidence of energy transfer in nanosilicon was clearly detected by analyses of photoexcitation-relaxation process.- Process technologies for stable blue luminescence, optical cavity, photoconduction, nanowire, and 3-dimensional periodic nanostructure were developed as components of silicon photonics.(2) Applications of ballistic electron emitter- The usefulness of nanosilicon ballistic electron emitter as means of negative ion source and hydrogen gas generation was shown by operation in air and in pure water, respectively.- The applicability in vacuum was also demonstrated by the use as planar cold cathode for parallel electron-beam lithography and ultra-high-sensitivity image sensing.(3) Improved ultrasonic emission and device applications- The appropriate design and driving techniques compatible with efficient and stable ultrasonic emission from nanosilicon device were developed on a basis of systematic analyses.- Due to the flat frequency response, the nanosilicon emitter was successfully applied to sound source for studies on bio-acoustic communication and digital information transmission.(4) Implementation of functional integration- The device concept and process flow were given for monolithic integration of photonic, electronic, and acoustic functions into silicon substrate.- Actuality of this approach was demonstrated by prototyping two devices : sound-emissive electroluminescent diode and surface-emitting device with ballistic excitation mechanism.
