A Pulse-Based Characterization System for Temperature-Dependent and Transient Analysis of Nanoscale Devices and Circuits
Abstract
In recent years, a variety of novel “beyond CMOS” nanoelectronic devicetechnologies have emerged in the research community, including metal-oxide memristors, carbonnanotubes and graphene-based transistors. The DC properties of many of these technologies havebeen explored in great detail but for several technologies transient properties (e.g. switchingcharacteristics of metal-oxide memristors) have not been thoroughly investigated across a widerange of environmental conditions. The purpose of this proposal is to acquire a new device andcircuit characterization system at the University of Tennessee, Knoxville specifically designed tocharacterize the transient properties of nanoscale devices and small circuits across a largetemperature range. The proposed system includes a cryogenic probe station that allows forcharacterization from cryogenic temperatures up to 400C, a high-speed pulse generate, anarbitrary waveform generator, and a high-speed oscilloscope. With the proposed system,transient properties of nanoelectronic switching devices can be characterized at picosecondscales. Furthermore, a cryogenic probe station allows for characterization under varyingenvironmental conditions – an essential capability for measuring nanoelectronic securityprimitives. The proposed system will be used to enhance DoD funded projects focused onexploring applications of nanoelectronic devices, specifically memristors, in the areas ofneuromorphic computing and hardware security. For the applications considered, a detailedunderstanding of the underlying switching properties is critical as these new technologies aredeveloped and transitioned for use by future war fighters. The proposed characterization system will enable rigorous testing of memristive devices and test circuits that provides a clearer picture for reliability and uniqueness across wide ranging environmental conditions.
