Fabrication of CdTe QDs/BiOI-Promoted TiO2 Hollow Microspheres with Superior Photocatalytic Performance Under Simulated Sunlight

open access: yesNanoscale Research Letters, 2019
Hollow and heterostructured architectures are recognized as an effective approach to improve photocatalytic performance. In this work, ternary TiO2/CdTe/BiOI with hollow structure was constructed via a step-by-step method. In addition, the effect of TiO2

Ultrafast optical generation of coherent phonons in CdTe1-xSex quantum dots

open access: yes, 2003
We report on the impulsive generation of coherent optical phonons in CdTe0.68Se0.32 nanocrystallites embedded in a glass matrix. Pump probe experiments using femtosecond laser pulses were performed by tuning the laser central energy to resonate with the ...

CdTe Quantum Dots Encapsulated on Perovskite Grains Enable Highly Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Present work demonstrates an efficient laser‐assisted localized interfacial engineering strategy that achieves epitaxial‐grade atomic coherence in spatially defined p‐n microscopic heterointerfaces, via precisely embedding p‐type CdTe QDs into an n‐type perovskite matrix, which concurrently establishes dual optimization of microscale carrier management

Resonant optical pumping of a Mn spin in a strain free quantum dot

open access: yes, 2013
We report on the spin properties of individual Mn atoms in II-VI semiconductor strain free quantum dots. Strain free Mn-doped CdTe quantum dots are formed by width fluctuations in thin quantum wells lattice matched on a CdTe substrate. These quantum dots

Relative stability of zincblende and wurtzite structure in CdX(X = S, Se, Te) series - A NMTO study

open access: yes, 2008
Using NMTO-downfolding technique we have revisited the issue of relative stability between zincblende (ZB) and wurtzite (WZ) symmetries in case of CdS, CdSe and CdTe semiconductors.

Dielectric confinement of excitons in type-I and type-II semiconductor nanorods [PDF]

open access: yes, 2010
We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the emission peak by tens of meV ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

open access: yesAdvanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.
