Frequently Asked Questions
What methods are used for nanowire synthesis?
Vapor transport and condensation synthesize self-organized zinc oxide nanowires on sapphire substrates, as in Huang et al. (2001). Electrochemical and chemical dissolution of silicon wafers fabricates free-standing quantum wire arrays, per Canham (1990). Evaporation of metal oxide powders at high temperatures produces nanobelts of semiconducting oxides like zinc and tin, shown by Pan et al. (2001).
How do nanowires function in biosensors?
Boron-doped silicon nanowires with amine- and oxide-functionalization exhibit pH-dependent conductance for real-time detection of biological and chemical species. This enables highly sensitive and selective electrically based sensing over a large dynamic range. The approach uses nanowire nanosensors, as detailed by Cui et al. (2001).
What are applications of zinc oxide nanowires?
Zinc oxide nanowires enable room-temperature ultraviolet lasing in arrays grown by vapor transport. They also generate electricity from mechanical energy via piezoelectric effects in aligned arrays deflected by atomic force microscopy. These properties support optoelectronics and nanogenerators, per Huang et al. (2001) and Wang and Song (2006).
