Computational Microscopy of Spatial Dopant Distribution in Conjugated Polymer

open access: yesAdvanced Electronic Materials, EarlyView.
The study employed molecular dynamics simulations to investigate the distribution of dopants in conjugated polymers. The simulations revealed that dopants are randomly distributed without forming clusters, contrasting with experimental findings of dopant clustering.

Optimizing Polymer Composites for Effective Electromagnetic Shielding: The Role of Carbon Filler Properties and Temperature

open access: yesAdvanced Electronic Materials, EarlyView.
Polymer composites electromagnetic properties are promising for shielding applications. This study explores how filler geometry, orientation, and temperature impact shielding performance. Spherical carbon black enhances scattering, while anisotropic carbon nanotubes (CNTs) show directional wave propagation. CNT orientation critically affects efficiency,

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

open access: yesAdvanced 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

Elimination of Double‐Slope Nonideality in C60 Field Effect Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
This study shows that applying a pre‐scan reversed gate‐source bias (PRGSB) can eliminate double‐slope nonideality in n‐type organic field‐effect transistors of C60. It is proposed that this nonideality arises from high‐density traps near the source electrode and PRGSB injects positive charges into the dielectric layer. These accumulated charges act as
