Energy Spectrum of a Symmetric Graphene Double-Quantum-Dot System in a Normal Magnetic Field

Morgenstern Horing N.J., Liu S.Y., Silverman S., Raytheon Company, US

We examine the subband energy spectrum of a coupled symmetric Graphene double-quantum- dot system subject to Landau quantization in a normal magnetic eld. To formulate the dispersion relation, we construct the coupled double-dot Graphene Green`s [...]

Advanced Nanocomposite Materials Tailored to Solid-State Lighting Applications

Functionalization of silicon surfaces at the nanoclusters size is a crucial step that can give a great opportunity to use them in an enormous range of applications, including optical sensing, biological fluorescence imaging and optoelectronic [...]

Quantum Dot Gate InGaAs FETs

Jain F., Suarez E., Gogna M., Chan P-Y., Karmakar S., Fikiet J., Miller B., Heller E., University of Connecticut, US

This paper describes using wide energy gap lattice-matched II-VI layers, such as ZnSeTe- ZnMgSeTe, serving as a high-k gate dielectric for n-channel enhancement mode InGaAs field effect transistors (FETs). The thrust is to reduce interface [...]

Effect of swift heavy ion on CdS quantum dots embedded in PVA matrix and their applications

Gope G., Chakdar D., Avasthi D.K., Paul M., Nath S.S., NIT Silcchar, IN

We report synthesis of CdS quantum dots by chemical route at room temperature. In this technique CdS specimen are produced by simple chemical reactions where polyvinyl alcohol (PVA), acting as matrix, plays the key role [...]

Quantum dot (Qdot) labeling of gene expression analysis and single molecule imaging in neurons

Jeromin A., Riley Z., Byrnes E., Parry S., Smith S., Dee N., Jones A., Allen Institute for Brain Science, US

The Allen Brain Atlas1 is the first large scale atlas of gene expression in the mouse brain, using chromogenic in situ hybridization (cISH) of over 20,000 genes.Qdots have excellent potential for muliplex imaging of gene [...]
