Artificial Synapse based on ULTRARAM Memory Device for Neuromorphic Applications
Abhishek Kumar, Peter D. Hodgson, Manus Hayne +1
The memory demands of large-scale deep neural networks (DNNs) require synaptic weight values to be stored and updated in off-chip memory like dynamic random-access memory, which re…
Binding energies of excitonic complexes in type-II quantum rings from diffusion quantum Monte Carlo calculations
David Thomas, Ryan Hunt, Neil Drummond +1
Excitonic complexes in type-II quantum-ring heterostructures may be considered as artificial atoms due to the confinement of only one charge-carrier type in an artificial nucleus.…
Extended excitons and compact helium-like biexcitons in type-II quantum dots
Bhavtosh Bansal, S. Godefroo, M. Hayne +2
We have used magneto-photoluminescence measurements to establish that InP/GaAs quantum dots have a type-II (staggered) band alignment. The average excitonic Bohr radius and the bin…
Excitonic Mott transition in type-II quantum dots
Bhavtosh Bansal, M. Hayne, M. Geller +2
Photoluminescence spectra measured on a type-II GaSb/GaAs quantum dot ensemble at high excitation power indicate a Mott transition from the low density state comprising of spatiall…
High-field magneto-excitons in unstrained GaAs/AlGaAs quantum dots
Y. Sidor, B. Partoens, F. M. Peeters +5
The magnetic field dependence of the excitonic states in unstrained GaAs/AlGaAs quantum dots is investigated theoretically and experimentally. The diamagnetic shift for the ground…
