In this paper, we propose an efficient approach, namely the hybrid BIE/Poisson/Schrödinger
approach, for electrostatic analysis of nanoelectromechanical systems. In this approach, the interior
and the exterior domain electrostatics are described by Poisson's equation (or Poisson's equation
coupled with Schrödinger's equation when quantum-mechanical effects are dominant) and the
boundary integral formulation (BIE) of the potential equation, respectively. We employ a meshless
finite cloud method and a boundary cloud method to solve the coupled BIE/Poisson/Schrödinger's
equations self-consistently. The proposed approach significantly reduces the computational cost and
provides a higher accuracy of the solution. © 2004 American Institute of Physics.
