application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

The electron transport in single-wall carbon nanotubes is one-dimensional and ballistic. Typically carbon nanotubes form tunneling contacts to electrodes and behave as quantum dots at low temperatures. We report on experiments on carbon nanotubes contacted with ferromagnetic metal. In these devices strong hysteretic magnetoresistance is observed at low temperatures. A possible interpretation of...

in genomics, the ability to amplify rare transcripts has enabled rapid advances in the understanding of gene expression patterns in human disease. the inability to increase the copy number and to detect the signal of rare proteins as unique species in biological samples has hindered the ability of proteomics to dissect human disease with the same complexity as genomic analyses. advances in nano...

The spin-orbit coupling till recently was commonly presumed negligible in carbon nanotubes (CNT) due to the lightness of carbon atom and symmetries of flat graphene. Indeed, before the work of Kuemmeth et al, the interpretation of the majority of experiments with charge carriers in CNTs assumed the independent spin and orbital degeneracies of the electron states in a CNT. The approximate four-f...
