Advanced Visualization of Electronic Band Structure in Bulk and Suspended WTe2

CORDIS · observation · Publication date unknown

Te2 As electronics shrink to atomic scales, silicon-based devices are now approaching fundamental physical and technological limits. At the same time, rapidly growing computing demands, especially in artificial intelligence, drive a steep rise in global energy consumption, conflicting with urgent sustainability goals. Breakthroughs in materials science are needed to enable scalable, low-power devices that exploit quantum phenomena for energy-efficient information processing and transfer. This project, WAVE (WTe2: Advanced Visualization of Electronic Band Structure), addresses this challenge by studying tungsten ditelluride (WTe2). This layered transition metal dichalcogenide, is predicted to host type-II Weyl fermions, elusive quasiparticles with tilted band crossings that enable anisotropic, high-mobility transport. Experimental verification of these quasiparticles has been challenging due to their energy lying above the Fermi level and the limited momentum resolution of conventional techniques. The host group recently developed a faster quasiparticle interference QPI method with si
