Doping control for nanotubes

Article Abstract:

The dimensions of silicon-based devices, transistors in particular, are constantly shrinking and their integration densities are increasing-in line with Moore's law, which predicts at least a doubling of the transistor density on a chip every two years. The study concluded that the undoped nanotube is frustrated spin liquid, meaning that its electron spins have random orientations.

Doping semiconductor nanocrystals

Article Abstract:

An attempt is made to show that the underlying mechanism that controls doping is the initial absorption of impurities on the nanocrystal surface during growth solution is discussed. It is found that adsorption and doping efficiency is determined by three main factors namely, surface morphology, nanocrystal shape and surfactants in the growth solution.

Surface transfer doping of diamond

Article Abstract:

Doping is a process of introducing impurities into the bulk crystal lattice for controlling the electronic properties of materials. The doping mechanism for a diamond without introducing foreign atoms into the diamond lattice is investigated.
