Highly Efficient n‐Type Doped Single‐Crystalline Perylene Diimide Microwires via Solution Processing for High‐Performance Photosensors and Photo‐Neuromorphic Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Solution‐processed high‐performance n‐type doped single‐crystalline organic semiconductor microwires (MWs) are reported. n‐Type dopants are located at the terrace edge of the MW, resulting in rapid doping and high interaction. n‐doped MWs show 5,000 times enhanced photosensitivity than evaporated films and high photo‐neuromorphic characteristics by ...

High Contrast and High Efficiency Optical Weighting for Integrated Photonic Computing

open access: yesAdvanced Optical Materials, EarlyView.
Herein, a combined pulse optical weighting scheme is proposed for photonic synapses. Employing a 4 μm$\umu{\rm m}$ long non‐volatile phase‐change material covered on a straight waveguide, a transmission contrast of 31.2 dB is achieved. By exploiting the non‐Arrhenius behavior of the material, the crystallization energy is reduced to 107 pJ, with ...

Deconstructing the synapse

open access: yesNature Neuroscience, 2018
While the role of protein synthesis in synaptic plasticity and memory is well-established, protein degradation processes have been less studied. A seminal 2003 Nature Neuroscience paper showed that ubiquitin-dependent degradation of synaptic proteins is engaged during activity-regulated synaptic remodeling.

Broadband Measurement and Tuning of the Volatile Thermo‐Optic Properties in Chalcogenide Phase Change Materials

open access: yesAdvanced Optical Materials, EarlyView.
Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.
