Towards printed magnetic sensors based on organic diodes
Sayani Majumdar, Himadri S. Majumdar, Daniel Tobjork +1
We report the study of magnetotransport properties of regio-regular poly (3-hexyl thiophene) based organic diodes. The devices were fabricated using two different techniques of spi…
Hopping conduction in strong electric fields: Negative differential conductivity
A. V. Nenashev, F. Jansson, S. D. Baranovskii +3
Effects of strong electric fields on hopping conductivity are studied theoretically. Monte-Carlo computer simulations show that the analytical theory of Nguyen and Shklovskii [Soli…
Statistical structure and -decay properties of closed shell Pb nuclei
N. U. H. Syed, M. Guttormsen, F. Ingebretsen +6
The level densities and gamma-ray strength functions of 205-208Pb have been measured with the Oslo method, utilizing the (3He, 3He' gamma) and (3He,alpha gamma) reactions on the ta…
Edge effects in the two-dimensional spin-1/2 Heisenberg antiferromagnet
Kaj H. Hoglund, Anders W. Sandvik
We use quantum Monte Carlo simulations to study effects of free edges in the two-dimensional spin-1/2 Heisenberg antiferromagnet. We find that the magnetic response of an edge is s…
On subexponentiality of the Lévy measure of the diffusion inverse local time; with applications to penalizations
Paavo Salminen, Pierre Vallois
For a recurrent linear diffusion on we study the asymptotics of the distribution of its local time at 0 as the time parameter tends to infinity. Under the assumption that th…
The role of electron-hole recombination in organic magnetoresistance
Sayani Majumdar, Himadri S Majumdar, Harri Aarnio +3
Magneto-electrical measurements were performed on diodes and bulk heterojunction solar cells (BHSCs) to clarify the role of formation of coulombically bound electron-hole (e-h) pai…
