Radiation Hardened Infrared Photodetectors Based on a Narrow Bandgap Conjugated Polymer Semiconductor

Advanced Electronic Materials, EarlyView.
A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...

Defect Density of States of Tin Oxide and Copper Oxide p‐type Thin‐film Transistors

Advanced Electronic Materials, EarlyView.
The complete band‐to‐band defect density of states driving p‐mode operation in tin and copper oxide transistors is obtained through photoconduction microscopy over a 0.15 to 3.5 eV tunable laser range. These analytical maps of subgap defect density with the extracted TFT bandgaps, show how ideal p‐mode operation may be achieved in metal oxide thin‐film

Materials Selection Principles for Designing Electro‐Thermal Neurons

Advanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Self‐Aligned Heterojunction Gate Carbon Nanotube Phototransistors for Highly Sensitive Infrared Detection

Advanced Electronic Materials, EarlyView.
This paper presents a self‐aligned heterojunction gate phototransistor that eliminates the need for high‐precision alignment tools. The device achieves a high responsivity of 2.9 × 105 A W−1 and a specific detectivity of 9.6 × 1013 Jones, comparable to the performance of non‐self‐aligned devices requiring complex fabrication.

High Resistivity of Single Crystal CsPbBr3 Semiconductor for Radiation Detection via Proposed Temperature‐Concentration Balance Method

Advanced Electronic Materials, EarlyView.
This study introduces a temperature‐concentration balance (TCB) method to grow high‐quality CsPbBr₃ single crystal with improved phase purity and structural stability. The crystals exhibits a sharp emission peak at 527 nm, narrow full width at half maximum (21.1 nm), and high resistivity (up to 3.97 × 10¹⁰ Ω·cm).

Electrically‐Driven Metal‐Insulator Transitions Emerging from Localizing Current Density and Temperature

Advanced Electronic Materials, EarlyView.
Negative differential resistance (NDR) is a key electronic response enabling two‐terminal artificial neurons. Interactions between electro‐thermal localizations and metal–insulator transitions (MITs) are investigated in a 3D multiphysics simulation of a lateral device. These findings demonstrate that the MIT nucleates in regions of high current density,
