Annealing of radiation-induced defects in silicon
Surface Engineering and Applied Electrochemistry, 2012 Annealing of the main radiation defects in silicon (A-centers, E-centers, and divacancies, etc.) is theoretically described on the basis of the experimental data obtained by many authors. The parameters that characterize this process (the activation energies and frequency factors) have been ascertained, and various mechanisms and reactions that ...

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device
Advanced Functional Materials, EarlyView.In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

RADIATION DAMAGE AND STRUCTURAL LATTICE DEFECTS [PDF]
Le Journal de Physique Colloques, 1974 The paper is concerned with influences of structural lattice defects mainly in metals on Mössbauer studies and contrary-wise with the information about these defects available from Mössbauer studies. First a short review of present knowledge about the production of defects in collision processes of highly energetic particles (« external » and ...

Advanced Functional Materials, EarlyView.Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Advanced Functional Materials, EarlyView.Trap state engineering in inverted organic photodetectors (OPDs) is achieved via combined layer‐by‐layer (LbL) processing and poly(N‐vinylcarbazole) (PVK) incorporation. LbL reduces the trap density while PVK additives gradually shift trap states from shallow band‐edge to deep mid‐gap levels, tailoring the energy distribution.
