Abstract: Amongst the candidates for very high efficiency solid state light sources and full solar spectrum solar cells are devices based upon InGaN nanowires. Additionally these nanowires typically require heterostructures, quantum dots, etc which all place requirements for these structures to be grown with relatively few defects and in a controllable reproducible manner. Additionally flexibility according to the device design requires that the nanowire at the substrate may be either InN or GaN. According to the invention a method of growing relatively defect free nanowires and associated structures for group IIIA-nitrides is presented without the requirement for foreign metal catalysts and overcoming the non-uniform growth of prior art non-catalyst growth techniques. According to other embodiments of the invention self-organizing dot-within-a-dot nanowire and dot-within-a-dot-within-a-well nanowire structures are presented.

Abstract: Atomic Force Microscopes (AFMs) allow forces within systems under observation to be probed from the piconewton forces of a single covalent bond to the forces exerted by cells in the micronewton range. The pendulum geometry prevents the snap-to-contact problem afflicting soft cantilevers in AFMs which enable attonewton force sensitivity. However, the microscopic length scale studies of cellular/subcellular forces parallel to the imaging plane of an optical microscope requires high sensitivity force measurements at high sampling frequencies despite the difficulties of implementing the pendulum geometry from constraints imposed by the focused incoming/outgoing light interfering with the sample surface. Additionally measurement systems for biological tissue samples in vitro must satisfy complex physical constraints to provide access to the vertical cantilever.

Abstract: Advances in a variety of fields such as micromachined silicon in conjunction with MEMS and other devices and attaching biosensors to electrode structures have allowed discrete or continuous monitoring devices to be implemented for biological systems, chemical processes, environmental monitoring etc. However, such devices are typically analysed within controlled laboratory environments due to bulky and large electrochemical impedance measurement systems. In many situations deployment in field, clinic, point-of-care, or consumer scenarios would be beneficial. Accordingly it an intention of the invention to provide a measurement system which offers potential for low cost implementations via multiple technologies to address the different cost targets of these applications as well as number of measurement cells within each. Additionally embodiments of the invention are self-calibrating and self-referencing allowing their use in such scenarios absent highly trained technicians.

Abstract: Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H- benzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction. The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4?-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.
