Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond

Advanced Functional Materials, EarlyView.
A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

A Machine Learning Approach to Predicting Single Event Upsets [PDF]

arXiv, 2023
A single event upset (SEU) is a critical soft error that occurs in semiconductor devices on exposure to ionising particles from space environments. SEUs cause bit flips in the memory component of semiconductors. This creates a multitude of safety hazards as stored information becomes less reliable.
