Scanning Capacitance Microscopy
SPIE Proceedings, 1985Scanning capacitance microscopy is a new mechanically scanned microscopy. In its present configuration, the microscope has a demonstrated capability of detecting variations in surface topography of the order of 0.3 nm over areas of the order of 0.5 μm2. This great sensitivity to height changes is achieved by the placement of a capacitance probe some 20

Minimum detectable capacitance in capacitive readout circuits
2011 IEEE 54th International Midwest Symposium on Circuits and Systems (MWSCAS), 2011In this paper, accurate equations are presented to calculate the capacitance resolution in the readout circuits exploiting different techniques to reduce the circuit low-frequency noise. The circuit parameters and trade-offs affecting the capacitance resolution are comprehensively involved in these equations.

Capacitance of a finite cylinder
Electrical Engineering (Archiv fur Elektrotechnik), 2003The aim of this paper is to present a new method of solving particular electrostatic problems. It is based on the superposition of the results obtained in the analysis of the single parts of the problem, to get the solution of a complex geometry. In particular, by means of the generalized solutions, dealing with the hollow cylinder and the end caps ...

The vast majority of microphones that are produced each year utilize capacitive sensing either through the use of a charged electret material or an applied bias voltage. The design of these microphones, in essentially all cases, relies on simple formulas to estimate the capacitance of parallel plate electrodes. This greatly limits the designs to follow

Recent Progress on High‐Capacitance Polymer Gate Dielectrics for Flexible Low‐Voltage Transistors
Advanced Functional Materials, 2018The gate dielectric layer is an essential element of field‐effect transistors (FETs), large area integrated circuits, and various application electronics. Beyond basic insulation between the semiconductor layer and gate electrode, FET performance largely

The invention relates to a modular multi-level converter (2) provided with a control module (4) and a calculator (10) for calculating a set value for the internal energy of the converter, stored in the capacitances of the sub-modules of the half-arms. The control module is designed to deduce, from said set value for the internal energy of the converter,

Shape dependence of the capacitance of scanning capacitance microscope probes
Ultramicroscopy, 2008The capacitance of approximately conical scanning capacitance microscope probes placed perpendicularly over a conducting plane has been modelled using the finite element method. The dependence on tip/surface distance, radius of curvature of the tip apex, cone angle and height has been analysed.
