Abstract:
The method of the invention induces crystallization in an amorphous semiconductor layer (16), and includes the steps of: a) producing a patterned metal layer (18) on a first substrate (17), the metal layer (18) exhibiting a weak level of adherence to the first substrate; b) pressing the metal layer (18) into physical contact with the amorphous semiconductor layer (16); c) applying heat, light or both to the metal layer (18) and amorphous semiconductor layer (16) to cause a reaction therebetween and a crystallization of the amorphous semiconductor that is juxtaposed to the metal.
Abstract:
This invention presents a novel method to form uniform or heterogeneous, straight or curved and size-controllable nanostructures, nanowires, and nanotapes, including SiNW, in a nanochannel template. In the case of semiconductor nanowires, doping can be included during growth. Electrode contacts are present as needed and built in to the template structure. Thus completed devices such as diodes, transistors, solar cells, sensors, and transducers are fabricated, contacted, and arrayed as nanowire or nanotape fabrication is completed. Optionally, the template is not removed may become part of the structure. Nanostructures such as nanotweezers, nanocantiliver, and nanobridges are formed utilizing the processes of the invention.
Abstract:
The present invention is directed to the use of deposited thin films for chemical or biological analysis. The invention further relates to the use of these thin films in separation adherence and detection of chemical of biological samples. Applications of these thin films include desorption-ionization mass spectroscopy, electrical contacts for organic thin films and molecules, optical coupling of light energy for analysis, biological materials manipulation, chromatographic separation, head space adsorbance media, media for atomic molecular adsorbance or attachment, and substrates for cell attachment.
