Alexei Troshyn was member of the Gross group at WMI as a Ph.D. student between 2018 and 2022.
Ph.D. Thesis: Industrielle Herstellungsverfahren für Hochtemperatur-Supraleiter basierte Bandleiter der 2. Generation
The Ph.D. Thesis of Alexei Troshyn was done in close collaboration with Theva Dünnschicht GmbH at Ismaning. Alexei Troshyn developed deposition techniques for the cost-efficient fabrication of second-generation HTS conductors based on REBa2Cu3O(7-x) (RE = Gd, Dy) films using electron beam PVD and liquid-assisted growth. He used hastelloy C276 substrates with a MgO buffer layer achieved by inclined substrate deposition and an additional LaMnO3 buffer layer placed between MgO and HTS. With the MgO buffer, he could achieve a critical temperature of 89 K and critical current density of 1.1 MA/cm² (77 K, zero applied field). With additional LaMnO3 buffer, he found up to 30% higher current densities.
After finishing his Ph.D. in 2022, Alexei joined Theva Dünnschicht GmbH as a process engineer.
