Polarization-induced charge carrier separation in polar and nonpolar grown GaN quantum dots
We have performed systematic studies of wurtzite GaN/AlN quantum dots grown on polar and nonpolar surfaces. For this purpose, experimentally observed quantum dot geometries have been employed within a...

Analysis of the high-frequency performance of InGaAs/InAlAs nanojunctions using a three-dimensional Monte Carlo simulator
We report results from the investigation of the intrinsic high-frequency (HF) behavior of three-terminal junctions based on InGaAs/InAlAs heterostructures, using a well-calibrated three-dimensional se...

This paper presents the results of atomic force microscopy (AFM) measurements of the adhesion between materials relevant to organic solar cells and organic light-emitting devices. The adhesion is quantified using pull-off forces obtained for organic-organic, organic-inorganic, and inorganic-inorganic interfaces. The measured pull-off forces and surface parameters are then incorporated into theoretical models for the estimation of surface energies. The implications of the results are then discussed for the design of enhanced robustness in organic electronic structures. ©2009 American Institute of Physics
