Solid state electric field sensor
Power measurement systems, such as Phasor Measurement Unit (PMU) structures, require installation of special voltage and current instrument transformers connected to the energized conductor to collect data from the power line. While non-contacting methods of current monitoring are already well known and implemented, the contactless voltage monitoring is still lacking. This paper describes a tun...
متن کاملDirect Nanoscale Imaging of Evolving Electric Field Domains in Quantum Structures
The external performance of quantum optoelectronic devices is governed by the spatial profiles of electrons and potentials within the active regions of these devices. For example, in quantum cascade lasers (QCLs), the electric field domain (EFD) hypothesis posits that the potential distribution might be simultaneously spatially nonuniform and temporally unstable. Unfortunately, there exists no ...
متن کاملBistability in the Electric Current through a Quantum-Dot Capacitively Coupled to a Charge-Qubit
We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...
متن کاملCalculation of Electric Field Characteristics of Insulator Under Sandstorm Condition
Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...
