We present a theoretical analysis of coupled electron-hole (e-h) quantum wire system's finite-temperature T intra- and inter-wire pair-correlation functions for some selected values of carrier number densities. The dynamics of intra- and inter-wire carrier (electron or hole) correlations is included using the frequency dependent local-field correction factor as obtained in the quantum analogue of the self-consistent mean-field theory of Singwi et al (the qSTLS approximation). The importance of frequency dependence of LFC factor in the dielectric formulation shows up in phenomena such as Wigner Crystallization, optical absorption and plasma dispersion. Our study shows that in the coupled e-h system, holes in hole wire are more strongly correlated than the electrons in electron wire. Additionally, the decrease in carrier number density results in a monotonic increase in the inter-wire correlations. [ABSTRACT FROM AUTHOR] |
