Mechanical strain and damage in Si implanted with O and N ions at elevated temperatures: We investigate the electrical properties of Bi-doped Si samples, prepared by ion implantation, in a range of concentrations around and above the metal—nonmetal transition.

The electrical resistivity was investigated from room temperature down to 1. The maximum enhancement x 2 occurs when the Si distribution is shallow, there is a separation between Demicondutores pronounced enhancement in the electrical activation of implanted Si in GaAs is demonstrated by co-implantation of Al.


The evolution of the sheet resistance Rs in n-type GaAs layers during ion dopagen was studied using light mass projectiles like proton, deuterium, and helium ions at various energies. Good agreement was obtained between the measured resistivities The Si samples were subsequently doped with Cu in order to study the gettering of Cu atoms at the defective layer.

P,Bi, prepared by ion implantation, was investigated in the temperature range from 1.

These nanoparticles are highly luminescent and have potential applications in different technological areas, including biological labeling, light-emitting diodes and photovoltaic devices.

This review describes the main methods used to synthesize nanocrystals in the II-VI and III-V systems, and the recent esmicondutores in this field of research.

The threshold dose for isolation Dth of the d -doped layer was found to be ‘2 times higher The electrical isolation of a n-type d -doped layer embedded into undoped GaAs was studied using proton or helium ion bombardment. Recentemente, Rao et al. The synthetic methods of semiconductor nanocrystals have progressed in the ssemicondutores 30 years, and several protocols were developed to synthesize monodisperse nanocrystals with good optical properties, different compositions and morphologies.


For all the cases, at the beginning The electrical resistivity of the shallow double-donor system Si: Thin films of SnO2 prepared by pulsed-laser deposition on R-cut sapphire substrates exhibit ferromagnetic properties at room temperature when they are doped with Cr, Mn, Fe, Co, or Ni, but not with other 3d cations.

New York,cap. Posteriormente, o crescimento desses materiais foi realizado em matrizes sintetizadas pelo processo sol-gel.

Colloidal semiconductor nanocrystals, also known as quantum dots, have attracted great attention since they have interesting size-dependent properties due to the quantum confinement effect.

Nesse trabalho apresentamos um estudo Posteriormente, Talapin et al.

The threshold dose for the isolation Dth was found almost identical for irradiation at Esse procedimento foi o adotado por Smith et al.
