ELECTROMETER Definition
An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical hand-made mechanical instruments to high-precision electronic devices. Modern electrometers based on vacuum tube or solid state technology can be used to make voltage and charge measurements with very low leakage currents, down to ...

متن کاملGabriel Lippmann and the Capillary Electrometer
Early workers in the field of potentiometry faced a serious problem. The type of cell commonly used in potentiometric studies could supply only a tiny current and often had a high internal electrical resistance. If the electromotive force (emf) of such a cell is to be measured accurately, the apparatus must draw essentially no current from the cell. One obvious approach is to oppose this emf wi...
متن کاملNanoscale optical electrometer.
We propose and demonstrate an all-optical approach to single-electron sensing using the optical transitions of a semiconductor quantum dot. The measured electric-field sensitivity of 5 (V/m)/√Hz corresponds to detecting a single electron located 5 μm from the quantum dot-nearly 10 times greater than the diffraction limited spot size of the excitation laser-in 1 s. The quantum-dot-based electrom...
متن کاملThe effect of electrostatic screening on a nanometer scale electrometer.
We investigate the effect of electrostatic screening on a nanoscale silicon MOSFET electrometer. We find that screening by the lightly doped p-type substrate, on which the MOSFET is fabricated, significantly affects the sensitivity of the device. We are able to tune the rate and magnitude of the screening effect by varying the temperature and the voltages applied to the device, respectively. We...
