Noncovalently silylated carbon nanotubes decorated with quantum dots

Quantum dots in carbon nanotubes

In this overview paper, we present low-temperature electronic transport measurements of carbon nanotube quantum dots with a back gate. In a semiconducting tube, charge carriers could be completely depleted. The addition energy and the excitation spectrum have been studied as a function of the number of charges (electrons or holes), one by one. We observe electron–hole symmetry, which is a direc...

Multiwall carbon nanotubes as quantum dots.

We have measured the differential conductance of individual multiwall carbon nanotubes. Coulomb blockade and energy level quantization are observed. The electron levels are nearly fourfold degenerate (including spin) and their evolution in magnetic field (Zeeman splitting) agrees with a g factor of 2. In zero magnetic field the sequential filling of states evolves with spin S according to S = 0...

Double Quantum Dots in Carbon Nanotubes

Directed Linking of Carbon Nanotubes with Single CdSe Quantum Dots

Metallic single-walled carbon nanotubes (SWNTs or NTs) are the ideal nanometer-scale wire, as they can withstand current densities up to 2 to 3 orders of magnitude higher than copper currently used in electronic chips [1]. These conductive NTs can be utilized as nano-electrodes to electrically contact another nanoscale object, such as a single semiconductor quantum dot (QD) or metallic nanopart...

Somatostatin Decorated Quantum Dots Nanoparticles for Targeting of Somatostatin Receptors

Due to the unique optical properties like high brightness and narrow emission bands of Quantum dots, it is used as simple fluorescence materials in bio-imaging, immunoassays, microarrays, and other applications. To easy invistigate cell lines that overexpressed somtostatin receptors, somatostatin (SST) was conjugated with Quantum dots carrying PEG amine (Qdots-PEG-NH2). The conjugation of SST t...
