Abstract

The two components of the complex escape time τ^esc(k) = τ^esc₁(k) - iτ^esc₂(k) for an electron from a localised state in a one-dimensional disordered system are shown to be connected by Kramers-Kronig integral relations. In the complex k plane, τ₁ and τ₂ form an elliptic contour. Component τ^esc₂(k), in the case of an opaque barrier at an energy close to the bound level in the well, coincides with the lifetime expression.
