| A nanowire is a one-dimensional structure with "diameter" of tens of
nanometers and length up to tens of micrometers. In this talk, I will
discuss my group's research on several types of devices based on both
nano-fabricated nanowires (using the so-called top-down approach) and
chemically-grown nanowires (so-called bottom-up approach). Using
synthesized SnO2 nanowire arrays, we have fabricated transparent TFT
devices on glass with operation frequencies > 100 MHz; Ge/Si core/shell
nanowires have be grown epitaxially on Si substrates and can be made
into very high-performance transistor devices. Finally, I will discuss
my group's efforts to build circuits using crossed wire "crossbar"
structures based on two-terminal resistive switches (memristors) which
can act as high density memories or synapses in biologically inspired
neuromorphic circuits. |
