I. Introduction
The valence band structure of silicon is much more complex near its maximum than the conduction bands near their minima and can not be approximated by an effective mass [1]. The local empirical pseudopotential method (EPM) yields a good approximation not only near the Γ-point but in the complete Brillouin zone (BZ) [2]. The EPM has been extended to the case of confined states in MOSFETs [3]. The CPU time for solving the corresponding eigenvalue problem is rather high due to the large size of the Hamiltonian. Here, we propose a k*p method for confined states by which the CPU time can be reduced by orders of magnitude.
