Quasi-One-Dimensional Electron Gas in a Gas Quantum Wire
Palavras-chave:
semiconductor, quantum wire, collective excitation energyResumo
The semiconductor technology developed mainly from the second half of the twenty century allowed the fabrication of several electronic devices that helps in the monitoring and information about the economic activities that can impact the environment preservation. Therefore here we study the semiconductors properties particularly the ultrthin quantum wires properties, due to it potential application in electronic devices fabrication. Particularly we have investigated the effects of the plasmon–(LO) phonon interaction on the intrasubband static structure factor and the plasmon energy associated with the lowest subband in GaAs-AlGaAs parabolic QWW as a function of the electronic densities. We observe the presence of oscillations in the static structure factor spectra and show that they are directly related to the resonant split of the intrasubband collective excitation energy.
