The cross-sectional dimensions of nanowires set the quantization conditions for the electronic subbands they host. These can be used as a platform to realize one-dimesional topological superconductivity. Here we develop a protocol that forces such na

We compare the adiabatic quantized charge pumping performed in two types of InAs nanowire double quantum dots (DQDs), either with tunnel barriers defined by closely spaced narrow bottom gates, or by well-separated side gates. In the device with an ar

Zn3P2 twinning superlattice nanowires with diameters of 100–300 nm were grown under Sn catalysis on fluorine-doped tin oxide glass by physical vapor transport. The nanowires grew along the [101] direction with nonparallel {101} side facets. The Zn3

We demonstrate a controllable p$-$n junction in a three$-$dimensional Dirac semimetal (DSM) Cd$_3$As$_2$ nanowire with two recessed bottom gates. The device exhibits four different conductance regimes with gate voltages, the unipolar (n$-$n and p$-$p

Growth of Hierarchical CdS Nanostructures on Fluorine-Doped Tin Oxide Glass Substrate

Autor: Man Suk Song, Yong Kim

Publikováno v: The Journal of Physical Chemistry C. 119:28199-28205

Hierarchical CdS nanostructures were grown on fluorine-doped tin oxide glass via a physical vapor transport method. Tin from the substrate catalyzed the growth of a flower-like hierarchical structure that consisted of a stem and branches at a growth
