One-Step Hydrothermal Synthesis of Yellow and Green Emitting Silicon Quantum Dots with Synergistic Effect

open access: yesNanomaterials, 2019
The concept of synergistic effects has been widely applied in many scientific fields such as in biomedical science and material chemistry, and has further attracted interest in the fields of both synthesis and application of nanomaterials. In this paper,

Effects of Chemical Pressure on Superconductivity in Electrochemically Intercalated (TMA)yFe2(Se1−xSx)2 (TMA = Tetramethylammonium)

open access: yesAdvanced Functional Materials, EarlyView.
Intercalation of a series of FeSe1−xSx host crystals with tetramethylammonium cations (TMA+) linearly scales the critical temperature Tc from 43 K down to 28 K with increasing sulfur incorporation. The chemical pressure induced by the partial substitution shows a weakening of the superconducting properties in both hosts and intercalates in a remarkably

Chaos and Interactions in Quantum Dots

open access: yes, 2001
Quantum dots are small conducting devices containing up to several thousand electrons. We focus here on closed dots whose single-electron dynamics are mostly chaotic.

Robust parallel laser driving of quantum dots for multiplexing of quantum light sources

open access: yesScientific Reports
Deterministic sources of quantum light (i.e. single photons or pairs of entangled photons) are required for a whole host of applications in quantum technology, including quantum imaging, quantum cryptography and the long-distance transfer of quantum ...

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

open access: yesAdvanced Functional Materials, EarlyView.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Triplet-singlet relaxation in semiconductor single and double quantum dots

open access: yes, 2007
We study the triplet-singlet relaxation in two-electron semiconductor quantum dots. Both single dots and vertically coupled double dots are discussed. In our work, the electron-electron Coulomb interaction, which plays an important role in the electronic
