interfer Topological Insulators in III-V Quantum Wells"
Recent breakthroughs in III-V quantum wells have demonstrated the emergence of topological insulator states with robust edge conduction. By engineering InAs/GaSb heterostructures, researchers achieved a band inversion energy of ~10 meV, enabling the observation of quantized edge conductance at temperatures up to 4 K. This paves the way for low-power spintronic devices leveraging spin-momentum locking.
The role of strain engineering in enhancing topological properties has been explored, with biaxial strain of ~1% increasing the bandgap of topological states by 30%. This strain-induced modulation allows for fine-tuning of the Dirac cone dispersion, crucial for achieving high carrier mobility exceeding 50,000 cm²/Vs. Such advancements are critical for next-generation quantum computing platforms.
Interfacing III-V topological insulators with superconductors has revealed exotic phenomena like Majorana zero modes. Experiments using NbTiN contacts on InAs/GaSb heterostructures demonstrated a superconducting proximity gap of ~0.5 meV, with coherence lengths extending up to 200 nm. These findings are pivotal for realizing fault-tolerant quantum bits (qubits) in topological quantum computers.
The integration of III-V topological insulators with ferromagnetic materials has shown promise for spintronic applications. By depositing CoFeB layers on InAs/GaSb structures, researchers achieved spin-orbit torque efficiencies of ~0.3, enabling ultrafast magnetization switching at current densities as low as 10⁶ A/cm². This could revolutionize data storage technologies.
