Minimizing electrostatic interactions from piezoresponse force microscopy via capacitive excitation

open access: yesTheoretical and Applied Mechanics Letters, 2020
Piezoresponse force microscopy (PFM) has emerged as one of the most powerful techniques to probe ferroelectric materials at the nanoscale, yet it has been increasingly recognized that piezoresponse measured by PFM is often influenced by electrostatic ...

Excitation of VLF quasi-electrostatic oscillations in the ionospheric plasma [PDF]

open access: yesAnnales Geophysicae, 1996
A numerical solution of the dispersion equation for electromagnetic waves in a hot magnetized collisionless plasma has shown that, in a current-free ionospheric plasma, the distortion of the electron distribution function reproducing the downward flow

Parametric anti-phase excitation of resonant MEMS mirrors for fast start-up [PDF]

open access: yesScientific Reports
This paper analyzes anti-phase parametric excitation for a resonant MEMS mirror by independently driving two out-of-plane electrostatic comb-drive actuators positioned at the left and right sides of the MEMS mirror, enabling a fast and reliable start-up ...

Research on a Feedthrough Suppression Scheme for MEMS Gyroscopes Based on Mixed-Frequency Excitation Signals [PDF]

open access: yesMicromachines
Feedthrough interference is inevitably introduced in MEMS gyroscopes due to non-ideal factors such as circuit layout design and fabrication processes, exerting non-negligible impacts on gyroscope performance. This study proposes a feedthrough suppression

Photonic Excitation of a Micromechanical Cantilever in Electrostatic Fields [PDF]

open access: yesPhysical Review Letters, 2020
We present a specific near-field configuration where an electrostatic force gradient is found to strongly enhance the optomechanical driving of an atomic force microscope cantilever sensor. It is shown that incident photons generate a photothermal effect that couples with electrostatic fields even at tip-surface separations as large as several ...

Electrostatic Tuning of Cellular Excitability [PDF]

open access: yesBiophysical Journal, 2010
Voltage-gated ion channels regulate the electric activity of excitable tissues, such as the heart and brain. Therefore, treatment for conditions of disturbed excitability is often based on drugs that target ion channels. In this study of a voltage-gated K channel, we propose what we believe to be a novel pharmacological mechanism for how to regulate ...

Electrostatic Plasma Wave Excitations at the Interplanetary Shocks

open access: yesThe Astrophysical Journal, 2023
Abstract Over the last few decades, different types of plasma waves (e.g., the ion acoustic waves (IAWs), electrostatic solitary waves, upper/lower hybrid waves, and Langmuir waves) have been observed in the upstream, downstream, and ramp regions of the collisionless interplanetary (IP) shocks.
