Quantum interference control of electrical currents in GaAs
IEEE Journal of Quantum Electronics, 1998In an earlier publication, preliminary observations of the generation of electrical currents were reported in GaAs and low-temperature-grown GaAs (LT-GaAs) at 295 K using quantum interference control of single- and two-photon band-band absorption of 1.55- and 0.775-/spl mu/m ultrashort optical pulses.

Electric current as a control variable in the electrospinning process
Polymer Engineering & Science, 2006Abstract In the electrospinning process submicron‐diameter polymer fibers can be produced when a high potential difference is applied to a polymer drop suspended at the tip of a capillary. The electrospinning process is affected by a wide range of parameters, because of which controlling the properties of the fibers is difficult. This

Quantum Interference Control of Electrical Currents in Silicon
2007 Conference on Lasers and Electro-Optics (CLEO), 2007Electrical currents are generated in clean silicon at T = 300 K using quantum interference of femtosecond fundamental and second-harmonic pulses. This efficient photoinjection of ballistic currents across the indirect bandgap is detected by the emitted terahertz radiation.

Current Control by Electrically Active Grain Boundaries
1989The electric properties of grain boundaries are discussed for the general case, where the behavior of the potential barrier between the grains is controlled by an arbitrary number and distribution in energy of bulk and interfacial defects. Special emphasis is put on the high field phenomena, where minority carriers can be generated by hot electrons ...

Electric current control of spiral wave dynamics
Physica D: Nonlinear Phenomena, 1992The control of spiral wave parameters by electric current was investigated in the Belousov-Zhabotinsky (BZ) reaction. It was found that the wavelength and the period of spiral waves increase by a factor of up to 3 with electric current (both dc and ac).

Results of optimum current control on electric furnaces
JOM, 1950With today’s emphasis on very fast and efficient melting practice, these operating data are particularly timely. The author shows records of actual heats to indicate the great advantages accruing from automatic current settings, as compared with the results obtained with the furnace operator adjusting current settings by hand and by guess.
