Monolithic 4H-SiC nanomechanical resonators with high intrinsic quality factors
A. Hochreiter, P. Bredol, F. David +3
We present an extensive study of 4H-SiC nanomechanical resonators electrochemically etched out of a monocrystalline wafer. Combining piezo-driven interferometric determination of t…
Effect of Helium Ion Implantation on 3C-SiC Nanomechanical String Resonators
Philipp Bredol, Felix David, Nagesh S. Jagtap +4
Hybrid quantum devices enable novel functionalities by combining the benefits of different subsystems. Particularly, point defects in nanomechanical resonators made of diamond or s…
Non-unitary Quantum Electronics: Novel Functions from the Edge of the Quantum World
J. Mannhart, H. Boschker, P. Bredol
Novel categories of electronic devices and quantum materials are obtained by pipelining the unitary evolution of electron quantum states as described by Schroedinger's equation wit…
Non-Reciprocity of the Wave Packet Scattering Delay in Ballistic Two-Terminal Devices
P. Bredol
In the linear regime, transport properties of ballistic two-terminal devices are generally considered to be independent of the direction of the current. This two-terminal reciproci…
Determination of the phase coherence length of PdCoO nanostructures
T. Harada, P. Bredol, H. Inoue +3
The two-dimensional layered compound PdCoO is one of the best oxide conductors, providing an intriguing research arena opened by the long mean free path and the very high mobil…
Decoherence Effects Break Reciprocity in Matter Transport
P. Bredol, H. Boschker, D. Braak +1
The decoherence of quantum states defines the transition between the quantum world and classical physics. Decoherence or, analogously, quantum mechanical collapse events pose funda…
