Nano-matters and devices

Nanoscale devices are promising for next generation electronics. Our focus has been on exploring the controllable growth of nanowire arrays and studying their electrical transport properties. We are particularly interested on the boron-based nanowires because of their unique and special characteristics. Single-crystal boron nanowires have been obtained from quenching the quartz tube in which a thermal vapor transfer method is used to deposit nanowires on Au-coated Si substrates. Furthermore, nanoscale Y-junctions and nano chains have been synthesized in our group.

The next step is to find out is whether this light and high-temperature semiconductor can have high electrical conductivity in the nanowire or nanotube form as predicted by theoretical calculations. We are fabricating boron nanotubes and devising microscopic measurement procedures to verify this novel character.
