SUMMARY:Micromechanical Resonators for Measuring Charge - Joshua Lee (Univ
 ersity of Cambridge)
DTSTART:20080219T160000Z
DTEND:20080219T170000Z
UID:TALK10753@talks.cam.ac.uk
CONTACT:Joshua En-Yuan Lee
DESCRIPTION:Micromechanical (MEMS) resonators have gained increasing inter
 ests in the past few decades for their potential as mechanical oscillators
 \, mass sensors\, strain sensors\, and accelerometers.  This talk focuses 
 on their application for the measurement of miniscule quantities of charge
  as micro-electrometers.  A MEMS electrometer with a measured charge noise
  floor below 10 electrons at ambient pressure and room temperature is pres
 ented\, with suggestions for optimizing the performance to achieve single-
 electron resolution.
