Pulse mode operation of Love wave devices for biosensing applications [PDF]

, 2001
In this work we present a novel pulse mode Love wave biosensor that monitors both changes in amplitude and phase. A series of concentrations of 3350 molecular weight poly(ethylene glycol) (PEG) solutions are used as a calibration sequence for the pulse ...

Dielectrowetting Driven Spreading of Droplets [PDF]

, 2011
The wetting of solid surfaces can be modified by altering the surface free energy balance between the solid, liquid, and vapor phases. Here we show that liquid dielectrophoresis induced by nonuniform electric fields can be used to enhance and control the

An improved 2.5 GHz electron pump: single-electron transport through shallow-etched point contacts driven by surface acoustic waves

, 2003
We present an experimental study of a 2.5 GHz electron pump based on the quantized acoustoelectric current driven by surface acoustic waves (SAWs) through a shallow-etched point contact in a GaAs/AlGaAs heterostructure.

Focusing of surface-acoustic-wave fields on (100) GaAs surfaces [PDF]

, 2003
Focused surface-acoustic waves (SAWs) provide a way to reach intense acoustic fields for electroand optoacoustic applications on semiconductors. We have investigated the focusing of SAWs by interdigital transducers (IDTs)deposited on (100)-oriented GaAs ...

Phonon-Induced Quantum Magnetic Deflagration in Mn12

, 2006
A comprehensive set of experiments on the effect of high-frequency surface acoustic waves, SAWs, in the spin relaxation in Mn12-acetate is presented. We have studied the quantum magnetic deflagration induced by SAWs under various experimental conditions ...

The Application of the Theory of Synthesis of a Delay Line with a Surface Acoustic Wave for a Single-Mode Oscillator of Electric Signals in Some Sensors of Non-Electrical Quantities

Metrology and Measurement Systems, 2017
The paper deals with the issue of constructing delay lines on the basis of surface acoustic waves and their application to single-mode oscillators. As a result of a theoretical analysis concrete delay lines are proposed.
