The Langmuir-probe diagnostic of a plasma is studied using a particle-in-cell Monte Carlo model. The electron-density, temperature, and potential profiles are determined for a probe immersed in an Ar plasma. The model is verified using the low-pressure results of Sternovsky et al. [J. Appl. Phys. 94, 1374 (2003)]. It was proved that the ion to electron temperature ratio may not be constant in the sheath-presheath region.
