Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler

open access: yesAdvanced Functional Materials, EarlyView.
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

open access: yesAdvanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Measurement of pressure dependent variations in local pulse wave velocity within a cardiac cycle from forward travelling pulse waves

open access: yesScientific Reports
The local pulse wave velocity (PWV) from large elastic arteries and its pressure-dependent changes within a cardiac cycle are potential biomarkers for cardiovascular risk stratification.

Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

open access: yesAdvanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

Unlocking Photodetection Mode Switching from a Simple Lateral Design

open access: yesAdvanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and
