Improving Low Current Measurements on Nanoelectronic and Molecular Electronic Devices

I-V characterization of nanoelectronic and moletronic devices requires low level current measurements in the nanoamp to femtoamp range. To complicate matters, these measurements are quite often made at cryogenic temperatures. Therefore, highly sensitive instruments are required, and appropriate measurement and connection techniques must be employed to avoid errors. This white paper outlines tools and techniques used in characterizing these types of experimental devices.■
