Improved nearest-grid-point and cloud-in-cell particle-mesh schemes are suggeste d, and a new nearest-element-center scheme proposed, to help reduce self force and improve the spatial accuracy of forces in Monte Carlo semiconductor device simulation. These schemes are exercised on both one- and two-dimensional model problems. An attempt to design a scheme with reduced self force for unstructured triangular meshes is unsuccessful.
