Why Empirical p-Values Are Not Uniform: Reference Samples, Dependence, and PIT Backtesting

Jakub Lis

Probability integral transforms (PITs) and empirical -values are widely used to assess the calibration of predictive distributions. While exact PIT values are uniformly distribu…

Electric Currents at Semiconductor Surfaces from the Perspective of Drift-Diffusion Equations

Jakub Lis

Surface sensitive electric current measurements are important experimental tools poorly corroborated by theoretical models. We show that the drift-diffusion equations offer a frame…

Effect of a skin-deep surface zone on formation of two-dimensional electron gas at a semiconductor surface

Natalia Olszowska, Jakub Lis, Piotr Ciochon +3

Two dimensional electron gases (2DEGs) at surfaces and interfaces of semiconductors are described straightforwardly with a 1D self-consistent Poisson-Schrödinger scheme. However, t…

Two-dimensional currents at semiconductor surfaces as resonances within the classical current equation

Jakub Lis

Logarithmic voltage profile characteristic to two-dimensional current flows has been reported for several semiconductor surfaces. We analyse this phenomenon within a simple model o…

Fermi level pinning at the Ge(001) surface - A case for non-standard explanation

Mateusz Wojtaszek, Rafal Zuzak, Szymon Godlewski +4

To explore the origin of the Fermi level pinning in germanium we investigate the Ge(001) and Ge(001):H surfaces. The absence of relevant surface states in the case of Ge(001):H sho…

Appearance of effective surface conductivity - an experimental and analytic study

Jakub Lis, Mateusz Wojtaszek, Rafal Zuzak +2

Surface conductance measurements on p-type doped germanium show a small but systematic change to the surface conductivity at different length scales. This effect is independent of…
