Using Dopants as Agents to Probe Key Electronic Properties of Organic Semiconductors

Advanced Electronic Materials, EarlyView.
Dopants are typically used in organic electronics to enhance conductivity, but here their potential is demonstrated as probes for fundamental material properties. By integrating experimental data and multiscale simulations, it is shown how dopant ionization and conductivity measurements enable accurate extraction of ionization potential and Coulomb ...

Graph of Orthogonal Idempotent Elements in Rings of Integers Modulo n With Spectral Clustering

Journal of Mathematics
The zero-divisor graph provides a relationship between abstract algebra and graph theory. Based on this concept, a new graph is defined using the orthogonal idempotent elements in a ring.

Arithmetic over the rings of all algebraic integers.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1986
The main result of this paper is the proof of a conjecture of David Cantor, giving a Hasse principle for the ring of all algebraic integers: an absolutely irreducible affine variety defined over a number field K has points rational over the ring of all algebraic integers if and only if it has such points locally, for every finite place v of K.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

A GENERALIZATION OF A JACOBSON’S COMMUTATIVITY THEOREM [PDF]

Journal of Sciences, Islamic Republic of Iran, 2000
In this paper we study the structure and the commutativity of a ring R, in which for each x,y ? R, there exist two integers depending on x,y such that [x,y]k equals x n or y n.
