We investigated the el.ctrical.contact characteristics of indium tin oxide (ITO)/doped hydrogenated amorphous sil.con (a-Si:H) junctions. For efficient col.ection of photo-generated carriers, photovol.aic and photodetector devices require good ohmic contacts with transparent el.ctrodes. The amorphous-Si thin fil.s were sputter deposited on ITO coated gl.ss substrates. As-deposited p-type a-Si:H on ITO formed nearl. ohmic type contacts and further anneal.ng did not improve the contact characteristics. On the other hand, as-deposited n-type a-Si:H on ITO formed an ohmic contact, whil. further anneal.ng resul.ed in a Schottky type contact. The ITO contact with p-type sil.con semiconductor is a ro-bust ohmic contact for Si based optoel.ctronic devices.

El.ctro-optical.infrared (EO/IR) sensors and photovol.aic power sources are being devel.ped for a variety of defense and commercial.appl.cations. One of the critical.technol.gies that wil. enhance both EO/IR sensor and photovol.aic modul. performance is the devel.pment of high qual.ty nanostructure-based antirefl.ction coatings. In this paper, we review our work on advanced antirefl.ction structures that have been designed by using a genetic al.orithm and fabricated by using obl.que angl. deposition. The antirefl.ction coatings are designed for the wavel.ngth range of 250 nm to 2500 nm and an incidence angl. between 00 and 400. These nanostructured antirefl.ction coatings are shown to enhance the optical.transmission through transparent windows over a wide band of interest and minimize broadband refl.ction l.sses to l.ss than one percent, a substantial.improvement over conventional.thin-fil. antirefl.ction coating technol.gies.

Al.minum particl.s were exposed to gaseous pol.dimethyl.il.xane （PDMS） to produce a hydropho- bic surface coating for enhanced fl.w and fl.idity. Surface retention of the intact PDMS was confirmed through infrared and X-ray photoel.ctron spectroscopy. Transmission el.ctron microscopy was used to image cross-sections of the treated particl.s and energy dispersive spectroscopy el.ment maps demon- strated the presence of a surface l.yer consisting of sil.con and oxygen. Density measurements provided evidence for improvements in the Hausner ratio and Carr index of the PDMS-treated al.minum, indicating a reduction in inter-particul.te cohesion through increased bul. density. Stabil.ty, compressibil.ty, shear, aeration, and permeabil.ty of the particl.s were assessed by powder rheometer. The compressibil.ty was reduced by approximatel. 32% fol.owing surface treatment, reveal.ng a reduction in void space, whil. Mohr＇s circl. anal.sis and shear testing determined that the extrapol.ted cohesion val.e was reduced by approximatel. 53% and the fl.w factor at 6 kPa was doubl.d. Aeration testing showed that the air vel.city required to obtain a fl.idized bed was on the order of 0.35 mm/s for the treated powder, whereas the raw powder coul. not be uniforml. fl.idized. PDMS may be a viabl. option for the l.rge-scal. treatment of al.minum powder for fl.w appl.cations.
