Making BaZrS3 Chalcogenide Perovskite Thin Films by Molecular Beam Epitaxy


Abstract: We demonstrate the making of BaZrS3 thin films by molecular beam epitaxy (MBE). BaZrS3 forms in the orthorhombic distorted-perovskite structure with corner-sharing ZrS6 octahedra. The single-step MBE process results in films smooth on the atomic scale, with near-perfect BaZrS3 stoichiometry and an atomically-sharp interface with the LaAlO3 substrate. The films grow epitaxially via tw... » read more

Manufacturing Bits: July 28


Molecular chips Researchers from various organizations have devised a transistor consisting of a single molecule and a few atoms. The work could one day lead to the integration of molecular-based devices with existing semiconductor technologies. This work was conducted by Paul-Drude-Institut für Festkörperelektronik (PDI), Freie Universität Berlin (FUB), NTT and the U.S. Naval Research L... » read more

Manufacturing Bits: August 5


Double Big Mac chips Using molecular beam epitaxy (MBE), Cornell has devised a method of growing an emerging class of oxide films called Ruddlesden-Poppers. These oxides are layered structures, which consist of 2D-based perovskite slabs interleaved with cations. In the future, these structures could be used in various applications, such as superconductivity, magnetoresistance and ferromagne... » read more
