Abstract

Ferroelectric materials have are utilized across diverse technological applications, including memory and sensor devices. As technology continues to miniaturize, thin films become more important in integrating ferroelectrics into future devices. Hysteresis loops of ferroelectric materials are performed to measure the size of a material’s polarization. Here, we created a customized program and electronic setup to experimentally measure ferroelectric hysteresis loops that is more cost-effective and easily transportable as compared to commercial equipment. Although commercial equipment can handle these measurements with more ease and accuracy, the purpose of this was to create a system that could be utilized for preliminary testing in a more user friendly environment. This set-up uses LabVIEW software and hardware via an ELVIS circuit board. A user inputs measurement parameters to build a Positive-Up-Negative-Down (PUND) pulse sequence which is output to a measurement circuit and then read back into the computer and analyzed within the program. The circuit consists of two operational amplifiers that transform voltage to current which is integrated to ultimately find polarization of a sample. Preliminary testing to measure the "polarization" of a resistor indicates the program runs correctly by matching loops created by a commercial Radiant Technologies Ferroelectric tester.
