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 ...

QD-BDNF probes activate TrkB signaling and induce neuronal survival.

open access: yes, 2014
(A) Embryonic (E) 16.5 NG neurons incubated with QD-BDNF probes showed survival rates equivalent to unmodified BDNF (400 pM), while incubations with streptavidin-QDs did not. Neurons incubated with unmodified BDNF, streptavidin-QD and QD-BDNF (72 hr) are

Two-dimensional systolic array for the column-by-column QD algorithm

open access: yes, 1991
A 2D systolic array for the column-by-column QD algorithm is presented. The design requires 4n+R+S-4 steps and (n-1)(2n+2R-1) processors to compute at least R iterations to the roots of S polynomials of degree less than or equal to n.

QD-based saturable absorbers for utrafast lasers

open access: yes, 2011
Novel materials, notably quantum-dot (QD) semiconductor structures offer the unique possibility of combining exploitable spectral broadening of both gain and absorption with ultrafast carrier dynamic properties.

Increasing the quantum efficiency of InAs/GaAs QD arrays for solar cells grown by MOVPE without using strain‐balance technology

open access: yes, 2016
Research into the formation of InAs quantum dots (QDs) in GaAs using the metalorganic vapor phase epitaxy technique is presented. This technique is deemed to be cheaper than the more often used and studied molecular beam epitaxy.

Visualization of weak interactions between quantum dot and graphene in hybrid materials

open access: yesScientific Reports, 2017
The mechanisms of the weak interactions within hybrid materials such as quantum dot (QD) and graphene (GR) have important implications for the design of related optoelectronic devices. We characterize the weak interactions in hybrid QD-GR systems using a
