摘要: Here, we propose a robust lab-on-a-chip system for multi-dimensional (electrical, optical, and mechanical) characterization of single-molecule utilizing Si micromachined micro-electromechanical-system (MEMS) chip. Our MEMS-based break junction (MEMS-BJ) utilizes conventional MEMS chip fabrication techniques to create an electrostatic comb actuator capable trapping between two nanoscale metal electrodes with sub-nanometer displacement resolution. In order achieve this functionality, components the (e.g flexural spring, drive fingers) are delicately designed based on analytical model basic performance parameters verified using finite element analysis simulation capacitive sensor measurements. Using system, able perform combined Raman spectroscopy molecular conductance measurements in real-time. Finally, present representative case study by analyzing correlated electrical, mechanical information while mechanically modulating strain which allows direct observation interplay structure electron transport. We believe that our MEMS-BJ will enable deeper at level promoting development new methods chemical biological applications. [2020-0307]
