In this paper, the possibility to design flexible humidity sensors by spin-coating ofmoisture-sensitive polymer on three types of substrates—poly(ethylene terephthalate) (PET),polylactide (PLA) and composite polysiloxane is investigated. The optical properties, surfacemorphology and roughness of the substrates covered with polymer are studied by transmittancemeasurements and surface profiling, respectively. Thin polymer films of amphiphilic copolymerobtained by partial acetalization of poly(vinyl alcohol) are used as humidity sensitive media. Thesensing properties are probed through transmittance measurements at different levels of relativehumidity (RH). The influence of substrate type is studied by comparing the hysteresis of flexiblesensors with those that are deposited on glass substrates.

Two fully loaded epitaxial growth runs with 16 wafers in total were conducted in the AIXTRON G5 WW reactor in order to keep epigrowth conditions constant. The wafers were selected with a large spread of specific resistivity and dislocation densities. The resulting epilayers showed very good intra-wafer homogeneities as well as excellent wafer-to-wafer and run-to-run reproducibility with regard to epilayer thickness and doping concentration, point defect concentrations of Z1/2 and EH6/7 and the resulting Shockley-Read-Hall carrier lifetime. We found that the dislocation densities of the underlying substrates are influencing the stacking fault densities of the epilayers, which then vary between 0.1 and 10 cm-2. A substrate effect on the effective minority carrier lifetime was found.
