DESCRIPTION:Philip Feng\, Ph.D.\nElectrical Engineering\, Case School of E
 ngineering\, Case Western Reserve University\nNanoscience today enables ex
 citing emergences of low-dimensional nanostructures and new materials with
  previously inaccessible properties.  We explore these properties\, coupl
 ed with mechanical degrees of freedom in designed nanostructures\, to engi
 neer new nanomachines and transducers\, for sensing and information proces
 sing. In particular\, nanoscale electromechanical systems (NEMS) operating
  in their multiple resonant modes can make a exquisite platform.  In this
  talk\, I will focus on introducing 2D NEMS based on atomically-thin cryst
 als.  While graphene has been very well known as the hallmark of 2D cryst
 als\, other interesting 2D crystals with tunable bandgaps have emerged\, s
 uch as layers from transition metal di-chalcogenides (TMDCs) and black pho
 sphorus. Atomically-thin structures derived from these materials possess a
  number of interesting electrical\, optical\, and mechanical properties\, 
 and are attractive for new nanodevices.  I will describe our recent exper
 iments on demonstrating various high-frequency MoS2 and other 2D NEMS reso
 nators.  By performing sensitive optical and electronic measurements\, in
  combination with modeling\, we quantify the performance of these 2D NEMS\
 , and evaluate their potential applications and fundamental limits. Challe
 nges and advances in experimental techniques will also be discussed.
