Abstract: Simple transistor structures may be made using iron-titanate substrates. These structures may operate as varistor-transistor hybrid devices. The iron-titanate substrates may include pseudobrookite (PsB) substrates or 55 atomic % ilmenite (FeTiO3) and 45 atomic % hematite (Fe2O3) substrates (e.g., IHC45 substrates). The transistor structure may produce modified I-V characteristics when a gate voltage (applied through a gate oxide), a biasing voltage, or a magnetic field is applied to the structure.

Abstract: A method for forming SbSI thin films is formed. In the first step of the method, a substrate (14) is provided. Next a buffer layer (16) is formed on the substrate (14). Then, a SbSI source (12) is provided. The SbSI source (12) and buffer layer (16) with substrate (14) are placed in an ampoule (10). The ampoule is heated in a two-zone furnace (11). This causes the SbSI source (12) to form a vapor which reacts with the buffer layer (14) to form a thin film of SbSI.

Abstract: A substantially single phase, single crystalline, highly epitaxial film of Bi.sub.2 CaSr.sub.2 Cu.sub.2 O.sub.8 superconductor which has a T.sub.c (zero resistance) of 83K is provided on a lattice-matched substrate with no intergrowth. This film is produced by a Liquid Phase Epitaxy method which includes the steps of forming a dilute supercooled molten solution of a single phase superconducting mixture of oxides of Bi, Ca, Sr, and Cu having an atomic ratio of about 2:1:2:2 in a nonreactive flux such as KCl, introducing the substrate, e.g., NdGaO.sub.3, into the molten solution at 850.degree. C., cooling the solution from 850.degree. C. to 830.degree. C. to grow the film and rapidly cooling the substrate to room temperature to maintain the desired single phase, single crystalline film structure.
