Project description
Topological insulators for room-temperature electronics
Topological insulators (TIs) enable a new direction in quantum electronics, but their research has been mostly restricted to cryogenic temperatures. This hinders the full realisation of their potential. With this in mind, the EU-funded TopRooT project will demonstrate the possibilities of TIs by facilitating the development of room-temperature devices that incorporate them. The project’s objective is to establish a clear path for creating and designing such devices. It will focus on integrating TIs into systems that utilise ferromagnets (FM). This integration would unlock critical applications in spintronics and other fields. The project also aims to conduct extensive research on optimising TI/FM heterostructures. These structures play a pivotal role in enabling upcoming novel technologies like SOT-MRAM.
Objective
The proposal TopRooT (Towards TOPological insulator-based electronic devices for ROOm Temperature operation) aims at providing a route to novel electronic devices based on topological insulators. Nowadays, most of the research on topological insulators is for cryogenic (quantum)-electronics, but they also show huge potential for room temperature applications. To this end, a crucial technology is the integration of topological insulators (TIs) with topologically-trivial materials, such as ferromagnets (FM), enabling applications in spintronics and beyond. The proposal focuses on the study and optimization of TI/FM heterostructures and their application in spin-orbit torque magnetoresistive random access memories (SOT-MRAM). SOT-MRAM is at the forefront of the emerging technologies that enable a new generation of brain-inspired and energy-efficient computing, extremely relevant to drastically decrease the energy consumption of information and communication technologies, as stated in the European Commissions strategy on Shaping Europes digital future.
State-of-the-art implementation of SOT in TI/FM heterostructures is achieved at the microscale, which is not enough to achieve the needed high density of devices. Therefore, the proposal will specifically target the fabrication of nanoscale TI/FM heterostructures and pursue their implementation in full nanoscale magnetic tunnel junction (MTJ) devices for SOT-MRAM, addressing the integration and efficiency challenges that arise. This will be achieved by growing Bi2Se3 (the chosen TI system) by molecular beam epitaxy and by sputtering the FM and MgO layers for the MTJs. Nanoscale fabrication will be achieved by electron beam lithography and auxiliary techniques. The efficiency of the SOT in TI/FM heterostructures will be accurately quantified via Harmonic Hall Voltage measurements at room temperature, while full MTJ devices will be subjected to electrical transport measurements to obtain the relevant device metrics.
