The behaviour of the (I-V) characteristics is investigated in n+-i-n+ highly compensated Si resistors at temperatures 4.2-45K. The conduction mechanisms are discussed in detail here. The prebreakdown and breakdown regions of I-V characteristics were simulated by a one-dimensional model including the evidence of impurity high compensation and freeze out effects as well as the shallow-dopants imp...

In a recent paper [1], Talukder proposed a new empirical formula for electron-impact ionization cross sections of He-like ions that was claimed to excellently agree with the available experimental and theoretical data. Discussing this agreement, the author of reference [1] makes extensive comparison with our recommended formula of reference [2] (referred to as “BRY” in [1] although it would be ...

In this paper we study a partially ionized plasma that corresponds to an arc discharge at atmospheric pressure. We derive an inviscid hydrodynamic/diffusion limit, characterized by two temperatures, from a system of Boltzmann type transport equations modelling that plasma problem. The original property of this system is that impact ionization is a leading order collisional process. As a consequ...

The relationship between the implantation and development of information technology (IT) and improvements in business performance has been a matter of interest to professionals and researchers in Management since the 1980’s. Despite numerous studies that have attempted to determine the full impact of IT, no conclusive results have as yet emerged. This situation has been termed the productivity ...

Comparison of electronand photon-impact processes as a method for determination of photo-ionization cross sections is described, discussed and shown to have many attractive features. Keywords—Transition probability, cross section, photoionization, electron-ionization, multi-photon process.

By collision-energy/electron-energy-resolved 2D Penning ionization electron spectroscopy as well as by theoretical calculations of the collisional ionization dynamics, the outer shape of molecular orbitals for ionization to X(Σ) and A(Π) states of CO was sensitively probed, and the anisotropy of the interaction between He*(2S) and CO was determined. Ionization to the B(Σ) state of CO was assign...

BACKGROUND Intersectoral Action for Health (IAH) and its Health Impact Assessment (HIA) tool are built on collaboration between actors and sectors, requiring multidimensional and horizontal way of working. The study aims to analyse the enablers and barriers when such a new way of working and tool have been initiated to replace a traditional, vertical operation at the local level in Slovakia-a c...

Health impact assessments (HIAs) across the globe may be used by governments and industries to secure approval for unconventional gas extraction developments. HIA is an umbrella term that covers an array of health review and assessment practices, ranging from the very general to quite specific and technical health studies. Our concern in this paper is principally with the specialist end of the ...
