Modeling and Verification of 1/f Noise Mechanisms in FAPbBr3 Single‐Crystal X‐Ray Detectors

open access: yesAdvanced Electronic Materials, EarlyView.
We demonstratethat surface‐trap‐induced carrier number fluctuations are the dominantmechanism in FAPbBr3 Schottky devices, a conclusion supported by thedistinct defect profiles revealed by Drive‐Level Capacitance Profiling (DLCP). Throughnoise contribution decomposition, it is found that the 1/f noise of thedetector is the key noise source affecting ...

Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene

open access: yesAdvanced Electronic Materials, EarlyView.
The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Side‐Chain Branching Dictates the σ–S Coupling in Conjugated Polymer Thermoelectrics

open access: yesAdvanced Electronic Materials, EarlyView.
The correlation between conductivity and Seebeck coefficient has been extensively studied in numerous works. Nevertheless, its association with side chains has not been thoroughly explored. In this work, we found that the distance between the branching points of side chains and the molecular backbones has a significant effect on thermoelectric ...
