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

Advanced Functional Materials, EarlyView.Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces
