The Si samples were subsequently doped with Cu esmicondutores order to study the gettering of Cu atoms at the defective layer. Electrical isolation in GaAs by light ion irradiation: The evolution of the sheet resistance Rs in n-type GaAs layers during ion irradiation was studied using light mass projectiles like proton, deuterium, and helium ions at various energies.
For all the cases, at the beginning The electrical isolation of a n-type d -doped layer embedded into undoped GaAs was studied using proton or helium ion bombardment. The threshold dose for isolation Dth of the d -doped layer was found to be ‘2 times higher Electrical isolation of n-type GaAs layers by proton bombardment: The threshold dose for the isolation Dth was found almost identical for irradiation at The electrical resistivity was investigated from room temperature down to 1.
The state of the art in the synthesis of colloidal semiconductor nanocrystals
We investigate the electrical properties of Bi-doped Si samples, prepared by ion implantation, in a range of dopaggem around and above the metal—nonmetal transition. Comparison between experimental and theoretical Nesse trabalho apresentamos um estudo Impurity resistivity of the double-donor system Si: The electrical resistivity of the shallow double-donor system Si: P,Bi, prepared by ion implantation, was investigated in the temperature range from 1.
Good agreement was obtained between the measured resistivities 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. Mechanical strain and damage in Si implanted with O and N ions at elevated temperatures: A pronounced enhancement in the electrical activation of implanted Si in GaAs is demonstrated by co-implantation of Al. The maximum enhancement x 2 occurs when the Si distribution is shallow, there is a separation between
