Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr
Advanced Functional Materials, EarlyView.We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

High Temperature Operation of Co-Doped InAs Quantum Dot Laser for O-Band Emission
IEEE Photonics JournalWe demonstrate high temperature operation of InAs quantum dot lasers through active region engineering. We grew an n-doped region within the InAs quantum dot (QD) layer and incorporated a 10 nm p-GaAs modulation-doped layer within a 43 nm GaAs spacer ...

Advanced Healthcare Materials, EarlyView.Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Inverted Singlet-Triplet Qubit Coded on a Two-Electron Double Quantum Dot [PDF]
, 2014 The $s_z=0$ spin configuration of two electrons confined at a double quantum dot (DQD) encodes the singlet-triplet qubit (STQ). We introduce the inverted STQ (ISTQ) that emerges from the setup of two quantum dots (QDs) differing significantly in size and

Advanced Healthcare Materials, EarlyView.This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Flexible and efficient perovskite quantum dot solar cells via hybrid interfacial architecture
Nature Communications, 2021 Perovskite quantum dots film has better mechanical stability and structural integrity compared to bulk thin film. Here, the authors demonstrate higher endurance of quantum dot films and develop hybrid CsPbI3 QD/PCBM device with PCE of 15.1% and 12.3% on ...

Origin of Efficiency Roll-Off in Colloidal Quantum-Dot Light-Emitting Diodes [PDF]
, 2013 We study the origin of efficiency roll-off (also called “efficiency droop”) in colloidal quantum-dot light-emitting diodes through the comparison of quantum-dot (QD) electroluminescence and photoluminescence.
