On the bound-state spectrum of a nonrelativistic particle in the background of a short-ranged linear potential

摘要

The nonrelativistic problem of a particle immersed in a triangular potentialwell, set forth by N.A. Rao and B.A. Kagali, is revised. It is shown that theseresearchers misunderstood the full meaning of the potential and obtained awrong quantization condition. By exploring the space inversion symmetry, thiswork presents the correct solution to this problem with potential applicationsin electronics in a simple and transparent way.
