ALD Zn(O,S) Thin Films’ Interfacial Chemical and Structural Configuration Probed by XAS
Dadlani, Anup; Acharya, Shinjita; Trejo, Orlando; Fritz, Prinz; Torgersen, Jan (Journal article; Peer reviewed, 2016)The ability to precisely control interfaces of atomic layer deposited (ALD) zinc oxysulfide (Zn(O,S)) buffer layers to other layers allows precise tuning of solar cell performance. The O K- and S K-edge X-ray absorption ... -
Relating Electronic and Geometric Structure of Atomic Layer Deposited BaTiO3 to its Electrical Properties
Torgersen, Jan; Acharya, Shinjita; Dadlani, Anup; Petousis, Ioannis; Kim, Yongmin; Trejo, Orlando; Nordlund, Dennis; Fritz, Prinz (Journal article; Peer reviewed, 2016)Atomic layer deposition allows the fabrication of BaTiO3 (BTO) ultrathin films with tunable dielectric properties, which is a promising material for electronic and optical technology. Industrial applicability necessitates ... -
Self-limiting atomic layer deposition of barium oxide and barium titanate thin films using a novel pyrrole based precursor
Acharya, Shinjita; Torgersen, Jan; Yongmin, Kim; Joonsuk, Park; Schindler, Peter; Dadlani, Anup; Winterkorn, Martin; Xu, Shicheng; Walch, Stephen; Usui, Takane; Schildknecht, Christian; Fritz, Prinz (Journal article; Peer reviewed, 2016)Barium oxide (BaO) is a critical component for a number of materials offering high dielectric constants, high proton conductivity as well as potential applicability in superconductivity. For these properties to keep pace ... -
The interface of SiO2/ZnS films studied by high resolution X-ray photoluminescence
Acharya, Shinjita; Trejo, Orlando; Dadlani, Anup; Torgersen, Jan; Berto, Filippo; Prinz, Fritz (Journal article; Peer reviewed, 2018)Sharp interfaces in optoelectronic devices are key for proper band alignment. Despite its benefits as buffer layer, ZnS deposited via atomic layer deposition (ALD) renders intermixed interfaces to its substrate, which can ...
