Conductance measurements at the nanoscale often involve specialized techniques and equipment. Common methods include:
- Four-Point Probe Method: This technique uses four separate probes to measure the voltage drop and current, minimizing contact resistance. - Scanning Tunneling Microscopy (STM): STM can measure conductance at atomic scales by detecting the tunneling current between a sharp tip and the sample. - Electromigration: This method involves applying a high current to move atoms in a nanowire, thereby modifying its conductance.
