Excitons in Time-Dependent Density-Functional Theory.

چکیده
This chapter gives an overview of the description of the optical and dielectric properties of bulk insulators and semiconductors in time-dependent density-functional theory (TDDFT), with an emphasis on excitons. We review the linear-response formalism for periodic solids, discuss excitonic exchange-correlation kernels, calculate exciton binding energies for various materials, and compare the treatment of excitons with TDDFT and with the Bethe-Salpeter equation.

Time-Dependent Density-Functional Theory and Excitons in Bulk and Two-Dimensional Semiconductors
In this work, we summarize the recent progress made in constructing time-dependent density-functional theory (TDDFT) exchange-correlation (XC) kernels capable to describe excitonic effects in semiconductors and apply these kernels in two important cases: a “classic” bulk semiconductor, GaAs, with weakly-bound excitons and a novel two-dimensional material, MoS2, with very strongly-bound excitoni...
متن کاملExcitonic effects in bulk CuBr using Time Dependent DFT
With a view towards studying the effect of lowering the dimensionality on excitons, we have first investigated the excitonic effects in bulk CuBr, which is a direct band-gap semiconductor with zinc blende structure. We have employed time-dependent density functional theory for this investigation. Both, the random phase approximation and the bootstrap approximation, for the exchange-correlation ...
متن کاملExcitons in Solids from Time-Dependent Density-Functional Theory: Assessing the Tamm-Dancoff Approximation
Excitonic effects in solids can be calculated using the Bethe-Salpeter equation (BSE) or the Casida equation of time-dependent density-functional theory (TDDFT). In both methods, the Tamm-Dancoff approximation (TDA), which decouples excitations and de-excitations, is widely used to reduce computational cost. Here, we study the effect of the TDA on exciton binding energies of solids obtained fro...
متن کاملBound excitons in time-dependent density-functional theory: optical and energy-loss spectra.
A robust and efficient frequency dependent and nonlocal exchange correlation f(xc)(r,r(');omega) is derived by imposing time-dependent density-functional theory (TDDFT) to reproduce the many-body diagrammatic expansion of the Bethe-Salpeter polarization function. As an illustration, we compute the optical spectra of LiF, SiO2, and diamond and the finite momentum transfer energy-loss spectrum of...
متن کاملTime-dependent density-functional approach for exciton binding energies
Optical processes in insulators and semiconductors, including excitonic effects, can be described in principle exactly using time-dependent density-functional theory TDDFT . Starting from a linearization of the TDDFT semiconductor Bloch equations in a two-band model, we derive a simple formalism for calculating exciton binding energies. This formalism leads to a generalization of the standard W...
