Intense sulphurization process can lead to superior heterojunction properties in Cu(In,Ga)(S,Se) thin-film solar cells
Oana Cojocaru-Miredin, Elaheh Ghorbani, Mohit Raghuwanshi +7
Sulphurization processes in Cu(In,Ga)Se thin-film solar cells has been intensively studied in the last decade as a viable alternative to the existing Ga-grading. The main advan…
Probing hundreds of individual quantum defects in polycrystalline and amorphous alumina
Chih-Chiao Hung, Liuqi Yu, Neda Foroozani +3
Quantum two-level systems (TLSs) are present in the materials of qubits and are considered defects because they limit qubit coherence. For superconducting qubits, the quintessentia…
Experimental Realisation of a π/2 Vortex Mode Converter for Electrons Using a Spherical Aberration Corrector
T. Schachinger, P. Hartel, P. -H. Lu +6
In light optics, beams with orbital angular momentum (OAM) can be produced by employing a properly-tuned two-cylinder-lens arrangement, also called /2 mode converter. It is not…
Structural and Nanochemical Properties of AlOx Layers in -Layer Systems for Josephson Junctions
S. Fritz, L. Radtke, R. Schneider +3
The structural and nanochemical properties of thin layers are decisive for the performance of advanced electronic devices. For example, they are frequently used as tunnel b…
Optimization of -Layer Systems for Josephson Junctions from a Microstructure Point of View
S. Fritz, L. Radtke, R. Schneider +2
-layer systems are frequently used for Josephson junction-based superconducting devices. Although much work has been devoted to the optimization of the superconducting…
Correlating the nanostructure of Al-oxide with deposition conditions and dielectric contributions of two-level systems in perspective of superconducting quantum circuits
S. Fritz, A. Seiler, L. Radtke +4
This work is concerned with Al/Al-oxide(AlO)/Al-layer systems which are important for Josephson-junction-based superconducting devices such as quantum bits. The device perfor…
