Hot Carrier Nanowire Transistors at the Ballistic Limit
M. Kumar, A. Nowzari, A. R. Persson +7
We demonstrate experimentally non-equilibrium transport in unipolar quasi-1D hot electron devices reaching ballistic limit. The devices are realized with heterostructure engineerin…
Thermopower signatures and spectroscopy of the canyon of conductance suppression
G. Kiršanskas, S. Hammarberg, O. Karlström +1
Interference effects in quantum dots between different transport channels can lead to a strong suppression of conductance, which cuts like a canyon through the common conductance p…
Transport in serial spinful multiple-dot systems: The role of electron-electron interactions and coherences
Bahareh Goldozian, Fikeraddis A. Damtie, Gediminas Kiršanskas +1
Quantum dots are nanoscopic systems, where carriers are confined in all three spatial directions. Such nanoscopic systems are suitable for fundamental studies of quantum mechanics…
A diagrammatic description of the equations of motion, current, and noise within the second-order von Neumann approach
O. Karlström, C. Emary, P. Zedler +5
We investigate the second-order von Neumann approach from a diagrammatic point-of-view and demonstrate its equivalence with the resonant tunneling approximation. Investigation of h…
Total Current Blockade in an Ultra-Cold Dipolar Quantum Wire
Líney Halla Kristinsdóttir, Olov Karlström, Johannes Bjerlin +4
Cold atom systems offer a great potential for the future design of new mesoscopic quantum systems with properties that are fundamentally different from semiconductor nanostructures…
A phonon scattering assisted injection and extraction based terahertz quantum cascade laser
E. Dupont, S. Fathololoumi, Z. R. Wasilewski +6
A novel lasing scheme for terahertz quantum cascade lasers, based on consecutive phonon-photon-phonon emissions per module, is proposed and experimentally demonstrated. The charge…
