Emitter passivation by charge injection

2011 37th IEEE Photovoltaic Specialists Conference, 2011
We have discovered a new means for engineering of emitter recombination and saturation current, J 0 , using corona controlled charge injection to deep dielectric traps near the interfacial region. The injected charge remains at the interface after removal of the corona charge from the dielectric surface, creating a highly desired low emitter ...

Charge Injection and Fatigue

2000
Fatigue is the characteristic of ferroelectrics that the amount of charge q that is switched with repetitive bipolar applied voltages decreases with cycling. This is usually described as a decrease in remanent polarization P r (N) with switching cycles N.

Charge injection frequency multiplier

Applied Physics Letters, 1992
We propose a novel frequency doubler, implemented in three terminal semiconductor heterostructures. This device represents a natural embodiment of the symmetry of hot-electron injection with respect to the polarity of the heating voltage. An efficient frequency doubling, comprising conversion gain with low harmonic distortion of the output signal was ...

Recombination of injected charge carriers

Solid-State Electronics, 1990
Abstract Generation and recombination of charge carriers dominate some performance aspects of semiconductor devices. Investigation of charge carrier recombination is frustrated by the paucity of direct measurement techniques for the recombination process. We formulate and solve the mathematics governing one such technique.

Charge-injection noise in CCDs

IEEE Transactions on Electron Devices, 2006
An analysis of the noise associated with electronic charge injection in charge-coupled devices (CCDs) is presented, including the effects of diffusion currents. The capacitance of the injection circuit determines the charge-injection noise, and specification of the noise requires consideration of the quoted capacitance; for large charge packets, the ...

Charge injection and storage in insulators

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1972, 1972
The electrostatic phenomena associated with the retention of surface charge by insulators is of considerable current research interest. The impetus is gained from industrial static electrification problems and the increasing utilization of the phenomena in modern technology.

Charge injection and conduction in anthracene [PDF]

This thesis describes a theoretical and experimental investigation of hole injection and conduction in anthracene crystals. Bulk conduction - space charge limited (SCL), from double injection or photogenerated - in this wide (3.7 eV) band gap insulator is dominated by traps in the forbidden gap.
