Physics of intraband quantum dot optoelectronic devices [PDF]

open access: yes, 2007
In last two decades, semiconductor nanostructures, such as quantum wells, wires and dots, have been recognised as sources and detectors of radiation in the mid- and far-infrared region of the spectrum.

Time-resolved spectra of a self-pulsing quantum dot laser [PDF]

open access: yes, 2010
Self-sustained pulsations in the output of an InAs quantum dot laser diode in the MHz range are reported for the first time. The characteristics (shape, range and frequency) are presented for the free running laser and when optical feedback in the ...

Hybrid Quantum Well/Quantum Dot Structure for Broad Spectral Bandwidth Emitters [PDF]

open access: yes, 2014
This thesis details a hybrid quantum well (QW)/quantum dot (QD) active element for an application in broadband source. First of all, a literature review on the fundamentals of optical coherence tomography (OCT) and superluminescent light emitting ...

The Iontronic Quantum Dot. [PDF]

open access: yesNano Lett
Semiconductor quantum dots (QDs) are key building blocks for quantum technologies with applications in quantum computation, communication, and sensing. QD device architectures rooted in conventional solid-state device fabrication paradigms are grappled with complex protocols to balance ease of realization, scalability, and transport properties.

Quantum computation with quantum dots [PDF]

open access: yesPhysical Review A, 1998
We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are effected by the gating of the tunneling barrier between neighboring dots.

High performance top-emitting quantum dot light-emitting diodes with interfacial modification

open access: yesAIP Advances, 2020
In this paper, we report high performance top-emitting quantum dot light-emitting diodes (TE-QLEDs) with an interfacial modification layer. The specular metal bottom electrode was modified by an interfacial layer to improve the wettability of the aqueous

Efficient Quantum Dot−Quantum Dot and Quantum Dot−Dye Energy Transfer in Biotemplated Assemblies [PDF]

open access: yesACS Nano, 2011
CdSe semiconductor nanocrystal quantum dots are assembled into nanowire-like arrays employing microtubule fibers as nanoscale molecular "scaffolds." Spectrally and time-resolved energy-transfer analysis is used to assess the assembly of the nanoparticles into the hybrid inorganic biomolecular structure. Specifically, we demonstrate that a comprehensive
