Hopping transport through heterostructure solar cells based on B-doped crystalline silicon wafers with highly P-doped hydrogenated amorphous silicon emitters with different thicknesses is investigated at T = 10 K with pulsed electrically detected magnetic resonance. The measurements show that transport is dominated by conduction band tail states (g ≈ 2.0046) with a distribution of their mutual ...

We further discuss the suggestion that the chemistry in a photon-dominated region is coupled to that in the UV-shielded region behind it by turbulent transport processes. In addition to transport time-scales, we discuss why MHD waves/turbulence will likely cause transport instead of prohibiting it. 1. On the C/CO Ratio Problem The study of interstellar chemistry has so far focused mainly on two...

An adaptive moving mesh method is presented for numerical simulation of two dimensional groundwater flow and transport problems. A selection of problems are considered, including advection dominated chemical transport and reaction, solute transport from contamination sources, transport of nonaqueous phase liquids (NAPLs) in an aquifer, and coupling of groundwater flow with NAPL transport. Numer...

Convective structures characterized by E×B motion are observed in a dipole-confined plasma. Particle transport rates are calculated from density dynamics obtained from multipoint measurements and the reconstructed electrostatic potential. The calculated transport rates determined from the large-scale dynamics and local probe measurements agree in magnitude, show intermittency, and indicate that...
