Terahertz detection with quantum point contacts
A current focus of terahertz (THz) research concerns the applications of semiconductor nanostructures, whose characteristic energies lie in the THz (i.e., meV) range. Quantum Point Contacts (QPCs) are an important example ...
Magnetically-controlled Fano resonance in wavefunction-coupled QPCs
In this thesis, we describe the observation of a resonant interaction between coupled quantum point contacts (QPCs) that we attribute to a Fano resonance, caused by the self-consistent formation of a bound-state (BS) in ...
