Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films

open access: yesAdvanced Electronic Materials, EarlyView.
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...

Ultrathin High‐Efficiency Zener Diode Fabricated Using Organized ZnS Nanoparticles in Surface‐Grafted Poly(methacrylic acid) Matrix

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a unique approach for fabricating homogeneously dispersed ZnS nanoparticles within an ultra‐thin (<40 nm) polymer matrix. The uniformity of dispersion is ensured through post‐polymerization substitution of Zn2⁺‐terminated side groups in surface‐grafted PMAA brushes. Due to the homogeneous distribution of semi‐conducting nanoparticles,

Mapping Interictal activity in epilepsy using a hidden Markov model: A magnetoencephalography study

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 66-81, January 2023., 2023
In this study, we use hidden Markov modeling (HMM) to create a unique statistical model of interictal brain activity for 10 pediatric epilepsy patients. This data‐driven model produces an output unique to each patient, and is used to localize the epileptogenic area(s).

Star Stream Velocity Distributions in Cold Dark Matter and Warm Dark Matter Galactic Halos

open access: yesThe Astrophysical Journal
The dark matter subhalos orbiting in a galactic halo perturb the orbits of stars in thin stellar streams. Over time, the random velocities in the streams develop non-Gaussian wings.

Observation of Mobility Above 2000 cm2/V s in 2DEG at LaInO3/BaSnO3 Interface by Electric‐Double‐Layer Gating

open access: yesAdvanced Electronic Materials, EarlyView.
The 2D carrier density of LaInO3/BaSnO3 2DEG to 1014 cm−2 by ionic‐liquid gating is increased and we found the resulting mobility enhancement up to 2100 cm2 V−1 s−1 at 10 K, which is consistent with the fact that 2‐dimensionality offers more effective screening for defects.
