Towards defect-free thin films of the earth-abundant absorber zinc phosphide by nanopatterning

Proximity field nanopatterning of azopolymer thin films.

A method for inscribing surface relief gratings in azopolymer thin films via proximity field nanopatterning is reported. Azopolymers prepared by ring opening metathesis polymerization were cast as thin films and brought into conformal contact with transparent polydimethylsiloxane phase masks. Irradiation of the film surface through the phase masks induces mass transport of azopolymer that gener...

Visible Luminescence of Rare Earth Ions Doped Amorphous Zinc Oxide Thin Films Grown by Sputtering Technique

Defect-free nanoporous thin films from ABC triblock copolymers.

The self-assembly of triblock copolymers of poly(ethylene oxide-b-methyl methacrylate-b-styrene) (PEO-b-PMMA-b-PS), where PS is the major component and PMMA and PEO are minor components, provides a robust route to highly ordered, nanoporous arrays with cylindrical pores of 10-15 nm that show promise in block copolymer lithography. These ABC triblock copolymers were synthesized by controlled liv...

Chemical vapour deposition of Group Vb metal phosphide thin films

The atmospheric pressure chemical vapour deposition (APCVD) reaction of VCl4 and VOCl3 with cyclohexylphosphine at substrate temperatures of 600 C deposits thin films of amorphous vanadium phosphide. The films are black/gold, hard, chemically resistant and conductive. The APCVD reaction of MCl5 (where M = Nb or Ta) with cyclohexylphosphine at 500 C – 600 C deposits films of crystalline -MP ...

The production of Ceramic Thin Films by Sol-Gel Method

The purpose of this work was to production of ceramic thin films by using of Sol-Gel process. For this purpose deposition of SiO2 on substrates of soda-lime glasses has been carried out. Coating treatments on prepared specimen were conducted in a Sol solution by means of dipping at various times. After drying and performing appropriate heat treatment on each sample, the thickness of coated laye...
