The computation of semiconductor sheet resistance

IEEE Transactions on Electron Devices, 1985
The effect of a nonuniform impurity concentration on semiconductor sheet resistance is analytically investigated. It is shown that potentially significant modeling errors result from the tacit neglect of concentration nonuniformity.

Sheet resistance corrections for spreading resistance ultrashallow profiling

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1996
Carrier profiles of ultrashallow structures obtained from raw spreading resistance probe (SRP) data frequently display artifacts related to sheet resistance values which are higher than those measured by the four point probe. Furthermore, the SRP raw data may already display a substantial resistance increase while the probes are still stepping over the

Combined resistive and conductive sheets

IEEE Transactions on Antennas and Propagation, 1985
To simulate a thin layer of material whose permittivity and permeability both differ from the values for the surrounding medium, a combination resistive and conductive sheet is defined and its properties described.

Resistive instability of periodic current sheets

Physics of Fluids B: Plasma Physics, 1992
The dispersion relation of the resistive tearing instability is derived and numerically solved for configurations characterized by periodic current sheets where a parameter-dependent resistivity can be included. Two unstable modes of different symmetry properties and different growth rates are identified, where the growth rates depend on the distance ...

Fatigue Resistance of the Sheets of Heat-Resistant Titanium Alloys

Physics of Metals and Metallography
The results of a study of the resistance to fatigue fracture of sheets made of heat-resistant titanium alloys VT18U (Ti–6.5Al–4.3Zr–2.4Sn–0.8Nb–0.7Mo–0.1Si, wt.%), VT8 (Ti–6.4Al–3.4Mo–0.3Si, wt.%), and VT25U (Ti–6.51Al–3.76Zr–1.71Sn–3.94Mo–0.5W–0.13Si, wt.%) has been presented.

Measuring Resistive Sheets in Free Space

37th ARFTG Conference Digest, 1991
Resistive sheet material, having surface resistance measured in ohms per square, is measured in a reflection and transmission manner by placing the material between two antennas. The measured transmission data is then converted to the time domain for separation of surface reflection and the attenuation thru the material.

A homogenization procedure for microstructured resistive sheets

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
A thin resistive sheet is described by its sheet conductance, and the electric and magnetic dipole moments per unit area. All three properties can be controlled by the material parameters and geometry of the sheet, for instance by making a periodic pattern of holes in it.

Finite-Resistivity Instabilities of a Sheet Pinch

The Physics of Fluids, 1963
The stability of a plane current layer is analyzed in the hydromagnetic approximation, allowing for finite isotropic resistivity. The effect of a small layer curvature is simulated by a gravitational field. In an incompressible fluid, there can be three basic types of ``resistive'' instability: a long-wave ``tearing'' mode, corresponding to breakup of ...

Sheet resistivity measurements at microwave frequencies

Microwave and Optical Technology Letters, 1995
AbstractExperimental techniques and data manipulation methods that allow highly accurate measurements of sheet resistivity values associated with thin films are presented. The procedure of microwave energy absorption is offered as a time‐efficient, noncontact, and nondestructive investigative means. © 1995 John Wiley & Sons. Inc.

Finite resistivity instabilities of a sheet pinch

Nuclear Fusion, 1966
The finite (nonzero) resistivity instabilities of a sheet pinch are studied by numerical analysis in terms of normal modes. Results are obtained for the tearing, rippling and gravitational modes and their dependence on conductivity, on wavelength, on the gravitational field, on the position of k · B = 0 and on the positions of the walls.
