Quantum dots have a small, countable number of electrons confined in a small space. Their electrons are confined by having a tiny bit of conducting material surrounded on all sides by an insulating material. If the insulator is strong enough, and the conducting volume is small enough, then the confinement will force the electrons to have discrete (quantized) energy levels. These energy levels can influence the device behavior at a macroscopic scale, showing up, for example, as peaks in the conductance. Because of the quantized energy levels, quantum dots have been called "artificial atoms." Neighboring, weakly-coupled quantum dots have been called "artificial molecules."

Quantum Dot Lab - A Novel Visualization Tool using Jupyter
09 Oct 2017 | | Contributor(s):: Khaled Aboumerhi
As semiconductor devices scale down into the nano regime, deep understanding of quantum mechanical properties of nano-structures become increasingly essential. Quantum dots are famous examples of such nano-structures. Quantum dots have attracted a lot of attention over the last two decades due to...

Synthesis and Characterization of CdSe Qunatum Dots
11 Jan 2017 | | Contributor(s):: Nicholas Blake
In this laboratory, students will study how surfactant-based chemistry can be used to synthesize CdSe quantum dots and study how the size of the quantum dots can be controlled by varying reaction time. The laboratory will demonstrate how the color of these quantum dots can be connected to...

Valley Dependent g-factors in Silicon: Role of Spin-Orbit and Micromagnets
13 Dec 2016 | | Contributor(s):: Rajib Rahman
In this talk I will show that spin splittings in silicon quantum dots are inherently valley-dependent. Interface disorder, such as monoatomic steps, can strongly affect the intrinsic spin-orbit coupling and can cause device-to-device variations in g-factors. I will also describe the anisotropy of...

Structure and Morphology of Silicon-Germanium Thin Films
07 Feb 2015 | | Contributor(s):: Brian Demczyk
This presentation describes the growth of (Si,Ge & SiGe) thin films on Si and Ge (001) and (111) substrates by ultrahigh vacuum chemical vapor deposition (UHVCVD). Thin films were characterized structurally by conventional and high-resolution transmission electron microscopy (TEM) and...
