Including spin in the Raychaudhuri equation
(The American Institute of Physics, 1991-02)
The Raychaudhuri equation for a spin fluid matter content is developed. The equation is applied to the behavior of an irrotational, unaccelerated fluid. The development of singularities in the expansion is studied for ...
High-efficiency organic polymer light-emitting heterostructure devices on flexible plastic substrates
(The American Institute of Physics, 2000-02-07)
In this letter, we describe a high-efficiency organic polymer light-emitting heterostructure device with aluminum cathode fabricated on a thin, flexible plastic substrate. The device consists of a hole transporting ...
Metal piezoelectric semiconductor field effect transistors for piezoelectric strain sensors
(The American Institute of Physics, 2004-08-16)
In this letter, we examine the potential of a functional device that can have good transistor and stress sensor properties. The device examined is based on the use of a thin oxide with high piezoelectric coefficients under ...
Ion‐Migration Phenomena Observed with the Electron Microscope
(The American Institute of Physics, 1945-06)
Cross sections for dark matter particles and implications for allowed masses, interactions, and detection
(Elsevier, 1986)
We present scattering and annihilation cross sections for a number of candidates for dark matter: heavy neutrinos, photinos, scalar-neutrinos, and higgsinos. In the mass region below about 10 GeV, annihilation cross sections ...
Alternative equations of motion for the radiating electron
(Springer-Verlag, 1995-02)
We have previously written down a simple second-order equation for the radiating electron and pointed out that its solutions are well behaved. A key feature of this equation is the presence of a term involving the time ...
The formation of thick borders on an initially stationary fluid sheet
(The American Institute of Physics, 1999-09)
The formation of thick borders on an initially stationary two-dimensional fluid sheet surrounded by another fluid is examined by numerical simulations. The process is controlled by the density and the viscosity ratios, and ...
Configuration Interaction in Two‐ and Three‐Electron Atoms
(The American Institute of Physics, 1966-12-01)
The ground states of the first four members of the helium isoelectronic series and the 22S and 22P states of lithium are calculated using a configuration‐interaction expansion in a complete denumerable set of single‐particle ...
Dipole Moments of Dimethylsiloxane Oligomers and Poly(dimethylsiloxane)
(The American Institute of Physics, 1971-06-15)
Dielectric constants at 20, 30, 40, and 50°C have been determined for pure liquid dimethylsiloxane oligomers (CH3)3Si–[OSi(CH3)2]xOSi(CH3)3 having chain lengths corresponding to x = 3,5,7,and9x=3,5,7,and9. Mean‐square ...
