The unique spin texture of quantum states in topological materials underpinsmany proposed spintronic applications. However, realizations of such greatpotential are stymied by perturbations, such as temperature and local fieldsimposed by impurities and defects, that can render a promising quantum stateuncontrollable. Here, we report room-temperature observation of interactionbetween Rashba states and topological surface states, which manifests uniquespin textures controllable by layer thickness of thin films. Specifically, wecombine scanning tunneling microscopy/spectroscopy with the first-principlestheoretical calculation to find the robust Rashba states coexisting withtopological surface states along the surface steps with characteristic spintextures in momentum space. The Rashba edge states can be switched off byreducing the thickness of a topological insulator Bi2Se3 to bolster theirinteraction with the hybridized topological surface states. The study unveils amanipulating mechanism of the spin textures at room temperature, reinforcingthe necessity of thin film technology in controlling quantum states.
