Optimization of the resistive switching in LaMnO3-based devices
Published : 30 November 2017
Recently, resistive random access memories (ReRAM) have generated significant interest both in industry and in the scientific community for their use as non-volatile memory beyond Flash memory scaling. ReRAMs are considered one of the most promising emerging non-volatile memories due to high speed, high density, great scalability and low power consumption. Recent work carried out in the group has pointed out towards lanthanum manganite as an attractive switching material. The goal of this project is to optimize the chemical deposition parameters of LaMnO3 by innovative research strategies with the aim of improving and tuning their resistive switching properties.
This project will focus on the synthesis and tailoring of LaMnO3-δ oxides with perovskite-type structure, which will be studied as memristive materials and will be carried out within the framework of an ANR project (Alps Memories project).
The Masters student will focus on the preparation of the manganite thin films by Metal Organic Chemical Vapour Deposition (MOCVD) and on their structural and microstructural characterization. MOCVD will be used as the deposition technique for its precise control and reproducibility. The obtained films will be fully analyzed (see Figure 1): X-ray diffraction (Theta-2theta, GIXRD, and Reflectometry), atomic force microscopy, electron microscopy (FEG-SEM, TEM) and in‐situ Raman spectroscopy will be routinely used for the physical characterization. The LMGP houses state of the art experimental equipment for investigating such properties.
The materials functional properties will be optimized by exploring the effects of a number of parameters allowing morphology control and epitaxial strain engineering. The tuning and optimization of the chemical deposition parameters by these research strategies will be used as the main tools to modify the physico-chemical, structural and microstructural properties to enhance the resistive switching performance.
The candidate will work in the FM2N group within the LMGP, Materials and Physical Engineering Laboratory. Located in the heart of an exceptional scientific environment, the LMGP offers the applicant a rewarding place to work.
