To determine the optical conditions by exploring various parameters that effects the growth of nanowires. This determination will serve to create uniform nanowires for mass production. Varying the pressure and substrate upon which nucleation takes place at constant temperature, scientist can determine the characteristics and optimal growth desired.


In 1965, Intel co-founder Gordon E. Moore predicted that the number of transistors on a microprocessor chip would double every 18 month. He later revised his prediction to every 2 years. Intel has kept that pace for nearly 40 years. How can today’s industry continue to see this trend?

By researching the use of nanosize structures, we can continue to see this trend. One nanosize structure that has been the focus of extensive studies worldwide is nanowires. Nanowires , a 1D structure, “represent the smallest dimension structure that can efficiently transport electrical carriers and thus are really suited to the critical and ubiquitous task of moving charges in integrated nanoscale systems.” 1 This structure can be utilized as device elements and wiring in the design of functional nanosystems. Is it possible to synthesize and control; the parameters needed for a particular type of nanowire?

According to Dr. Zhang Lin Wang, semiconductor nanaowires can be rationally and predictably synthesized in single crystal form with all key parameters controlled during growth: chemical composition, diameter, length, and doping.

Furthermore, he states nanowires can be assembled in a rational predictable manner because the size, interfacial properties and electronic properties of the nanowire can be precisely controlled during synthesis and moreover, reliable methods exist for parallel assembly. Why the extensive research on a structure so small? What are the possibilities?

Nanowires, similar to the one shown is made of antimony, germanium, and tellurium, could one day make ultra fast nonvolatile memory possible. This is credited to Dr. Ritesh Agarwal, at the University of Pennsylvania.

Reseachers at DOE's Berkeley and collaborators have developed a technique by which silicon wires can be embedded in a living cell with no apparent harm to the cell. This technique may one day link cells to one another and wire cells to external sensors and electronic devices. It has the possibility of delivering genetic materiel to the organelles in the cell. I hope it may be a potential step in the fight against cancer that has claimed so many loved ones.

This nanostructure has many possible applications, from electronics to biological applications, maybe improve our existing solar cells to help reduce the world's consumption of fossil fuels. We our need different forms of energy to save our planet and maybe even our very existence.
