Bandgap Engineering Silicon Nanopillars


Latawiec, Pawel Michal (2013) Bandgap Engineering Silicon Nanopillars. Senior thesis (Major), California Institute of Technology. doi:10.7907/CNP5-BZ88.


Vertically oriented , bandgap engineered silicon nanopillars were fabricated and addressed. Devices were fabricated via a three dimensional etching process which created sub-5 nm constrictions in silicon radius upon oxidation. This effect was used to create a Coulomb blockade device. Devices were tested at room and liquid nitrogen temperatures. They showed a clear blockade effect distinctive of an asymmetric double tunnel junction at low temperatures which disappeared when tested at higher temperatures. Different device fabrication parameters were also tested to develop high-current devices, including chip anneal time. Furthermore, both device fabrication steps and current flow were modeled and simulated.
