Abstract
We compare numerical results on metastable Stark-Wannier states in two semi-infinite disordered Kronig-Penney models in the presence of an electric field with an analytic derivation from a WKB-Lyapunov type formula. Results suggest vanishing of the width of the resonances at the infinite-system limit.Keywords
