Influence of Surface Resistance of Silicon p-i-n Photodiodes n+-Layer on their Electrical Parameters

open access: yesФізика і хімія твердого тіла, 2022
Silicon quadrant p-i-n photodiodes of different concentrations of diffused phosphorus in the n+- layer were fabricated. The experimental curve of phosphorus impurity distribution along the depth of the diffusion layer is obtained. The influence of charge

About the relationship between auroral electrojets and ring currents [PDF]

open access: yesAnnales Geophysicae, 2000
The relationship between the storm-time ring current and the auroral electrojets is investigated using IMAGE magnetometer data, DSt and H-SYM, and solar wind data. Statistical results as well as the investigation of single events show that the auroral

High latitude magnetospheric topology and magnetospheric substorm [PDF]

open access: yesAnnales Geophysicae, 2009
This study is focused on the problem of the localization of substorm expansion onset. In this context, the high latitude topology of transverse magnetospheric currents has been analyzed.

Probing the BCS-BEC crossover with persistent currents

open access: yesPhysical Review Research, 2021
We study the persistent currents of an attractive Fermi gas confined in a tightly confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover. At weak attractions, on the Bardeen-Cooper-Schrieffer (BCS) side, fermions

Next generation magnetic field measurements from low-earth orbit satellites enable enhanced space weather operations

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Large-scale current systems in the ionosphere and the magnetosphere are intimately controlled by the solar wind-magnetosphere interaction and the magnetosphere-ionosphere coupling.

Phenyl-cyclopentadienyl rule

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2012
Within a systematic study of cyclic conjugation in the benzo-annelated derivatives of acenaphthylene and fluoranthene, a general regularity was discovered, named phenyl-cyclopentadienyl rule (PCP rule).

The Magnetic Response of Starphenes

open access: yesChemistry, 2021
The aromaticity of [n]starphenes (n = 1, 4, 7, 10, 13, 16), as well as starphene-based [19]dendriphene, is addressed by calculating the magnetically induced current density and the induced magnetic field, using the pseudo-π model.

Laser-controlled local magnetic field with semiconductor quantum rings [PDF]

open access: yes, 2005
We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed to control the total angular momentum of the electrons.

Ring Currents in Polycyclic Sodium Clusters [PDF]

open access: yesThe Journal of Physical Chemistry A, 2011
In the recent work by Khatua et al. (Khatua, S.; Roy, D. R.; Bultinck, P.; Bhattacharjee, M.; Chattaraj, P. K. Phys. Chem. Chem. Phys.2008, 10, 2461-2474) the synthesis and structure of a fac-trioxo molybdenum metalloligand and its sodium complex containing 1D hexagonal chains of sodium ions was reported. In the same paper, the aromaticity of hexagonal

Long-term evolution of magnetospheric current systems during storms [PDF]

open access: yesAnnales Geophysicae, 2004
We present a method to model the storm-time magnetospheric magnetic field using representations of the magnetic field arising from the various magnetospheric current systems.
