Recent developments in density functional theory (DFT) methods applicable t
o studies of large periodic systems are outlined. During the past three dec
ades, DFT has become an essential part of computational materials science,
addressing problems in materials design and processing. The theory allows u
s to interpret experimental data and to generate property data (such as bin
ding energies of molecules on surfaces) for known materials, and also serve
s as an aid in the search for and design of novel materials and processes.
A number of algorithmic implementations are currently being used, including
ultrasoft pseudopotentials, efficient iterative schemes for solving the on
e-electron DFT equations, and computationally efficient codes for massively
parallel computers. The first part of this article provides an overview of
plane-wave pseudopotential DFT methods. Their capabilities are subsequentl
y illustrated by examples including the prediction of crystal structures, t
he study of the compressibility of minerals, and applications to pressure-i
nduced phase transitions. Future theoretical and computational developments
are expected to lead to improved accuracy and to treatment of larger syste
ms with a higher computational efficiency. (C) 2000 John Wiley & Sons, Inc.
