Ferroelectric negative capacitance [PDF]
Nature Reviews Materials, 2019 The capacitor is a key element of electronic devices and is characterized by positive capacitance. However, a negative capacitance (NC) behaviour may occur in certain cases and implies a local voltage drop opposed to the overall applied bias. Therefore, a local NC response results in voltage enhancement across the rest of the circuit. Within a suitably

Mesoscopic Capacitance Oscillations [PDF]
Nanotechnology, 2006 We examine oscillations as a function of Fermi energy in the capacitance of a mesoscopic cavity connected via a single quantum channel to a metallic contact and capacitively coupled to a back gate.

Experimental rig for measuring lubricant film thickness in rolling bearings [PDF]
, 2014 Electrical capacitance has been applied in the past for measuring the lubricant film thickness in rolling element bearings. The main difficulty arises from the fact that the measured capacitance is a combination of the capacitances of many rolling ...
