Andreev bound states emerge as excitations in semiconducting InAs, proximitized by superconducting Al. These can be a mixture of electron and hole their structure is determined material parameters, external magnetic field, gate voltages. Nonlocal conductance differential measurement the current carried through quasi-one-dimensional nanowire, it reveal charge character given BCS charge.

The identification of scalable processes that transfer random mixtures of single-walled carbon nanotubes (SWCNTs) into fractions featuring a high content of semiconducting species is crucial for future application of SWCNTs in high-performance electronics. Herein we demonstrate a highly efficient and simple separation method that relies on selective interactions between tailor-made amphiphilic ...

A great deal of interest in two-dimensional materials analogues of graphene has appeared among the scientific community since the demonstration of isolated 2D atomic plane crystals from bulk crystals [1]. Dimensionality is key for the definition of material properties and the same chemical compound can exhibit dramatically different properties depending on whether it is arranged in dots (0D), w...

The present work was an attempt to evaluate the potentialities of using SWCNTs as nanovectors for drug delivery of anticancer drug Oxaliplatin. First-principles van der Waals density functional (vdW-DF) calculations are used to investigate the incorporation of oxaliplatin inside the typical semiconducting and metallic single wall carbon nanotubes with various diameters (SWCNTs). Adsorption ener...

Semiconducting-only single-walled carbon nanotube (SWNT) network field effect transistors (FETs) have been fabricated by selectively reacting all the metallic SWNTs in the devices with diazonium reagents in a controlled manner. We have shown that the concentration of diazonium reagents used is crucial for selectively eliminating metallic SWNTs and keeping semiconducting ones intact. Excessive a...

BACKGROUND The potential use of carbon nanotubes (CNTs) in gene therapy as delivery systems for nucleic acids has been recently recognized. Here, we describe that metallic versus semiconducting single-wall CNTs can produce significant differences in transfection rate and cellular distribution of siRNA in murine PAM212 keratinocytes. RESULTS/METHODOLOGY The results of cell interaction studies,...
