In addition to heavy metals with strong spin-orbit coupling, some 2D systems have strong conversion rates between charge current and pure spin current. Among these systems are the surfaces or interfaces of topological insulators which are new states of matter. The growth of these materials will allow us to develop new types of magnetic memory and other spintronic devices that will reduce energy consumption. Moreover, it will also allow us to look for new devices to be exploited in spin-caloritronics (harvesting energy).
Within the framework of the ANR JCJC TOPTRONIC project, we are looking for a young post-doc with experience in the electrical characterization of topological insulators. Experience in the growth of topological insulators is an advantage. We have a bunch of interconnected growth techniques and ARPES characterization included. The candidate will be benefit from these facilities. The aim of the project is to develop topological insulators, mainly alpha-Sn, integrated with Heusler alloys for its exploitation in spintronics and spin-caloritronics. We have the experimental setups to study spin-to-charge and charge-to-spin current conversion as well as different methods to quantify the spin-orbit torque efficiency or to show the current-induced magnetization switching.
The successful candidate will perform the following main activities: participate in the growth of TI such as alpha-Sn integrated with Heusler alloy using a substrate beyond InSb or CdTe. The main tasks are as follows: electrical and magneto-transport characterization including clean-room (lithography).
Expected theoretical knowledge: strong background in solid-state physics
Expected experimental skills: mastery of tools and techniques in clean rooms (optical/electronic lithography) and experience in electrical characterization of topological insulators. Experience in growth techniques such as PLD or MBE is a plus.
The Institut Jean Lamour (IJL) is a joint research unit of the CNRS and the University of Lorraine. The IJL has about 500 members including researchers, teacher-researchers, engineering, technical and administrative staff, doctoral students and post-doctoral fellows, and hosts about 80 internships per year. It collaborates with more than 150 industrial partners and its academic collaborations are deployed in some 30 countries. Its exceptional instrumental park is spread over 4 sites, the main one being a new building located on the Artem campus in Nancy.
The project will be carried out within the Spintronic and Nanomagnetism team whose subjects range from the development of innovative materials for implementation in spin electronics devices, to the development of magnetic sensors and the fundamental study of physical phenomena related to magnetism.
