The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations ...

(Nanowerk News) An international research group led by scientists at the National Institute of Standards and Technology's (NIST) Center for Nanoscale Science and Technology has developed a method for ...

Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial ...

The quartz crystal microbalance (QCM) is a precise mass sensor that exploits the piezoelectric effect in quartz crystals to detect minute mass variations on its surface. At its core, the QCM operates ...

WEST LAFAYETTE, Ind. -- Purdue University researchers have demonstrated a new method for using lasers and semiconductors to more accurately measure the velocity of a moving object. The method relies ...

How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...

Researchers at the University of Miyazaki in Japan used a new non-destructive method to enable them to investigate solar cell vibrations independently of module components. The study included ...
