In a magnetic topological insulator, nontrivial band topology conspires with order to produce exotic states of matter that are best exemplified by quantum anomalous Hall (QAH) insulators and axion insulators. Up till now, such obtained doping atoms. The random dopants, however, inevitably introduce disorders hinder further exploration effects in the material. Here, we resolve this dilemma probing transport MnBi$_2$Te$_4$ thin flake - insulator intrinsic order. layered van der Waals crystal,...
Abstract Electrolyte gating has been employed as an effective way to modulate the electronic properties of transition metal dichalcogenides (TMDs) by carrier doping over a wide range. Here, density new metastable phase TMD material 2M‐WS 2 is controlled electrolyte achieve reversible transitions between superconducting state, metallic and insulating state. Pristine temperature ( T c ) 8.9 K with hole‐type 9.05 × 10 21 cm −3 at 100 K. A gate voltage V g applied sample side gate, which are...
Moir\'e superlattices, engineered through precise stacking of van der Waals (vdW) layers, hold immense promise for exploring strongly correlated and topological phenomena. However, these applications have been held back by the common preparation method: tear-and-stack Scotch tape exfoliated monolayers. It has low efficiency reproducibility, along with challenges twist angle inhomogeneity, interfacial contamination, micrometer sizes, a tendency to untwist at elevated temperatures. Here we...
Manipulating solids using the time-periodic drive of a laser pulse is promising route to generate new phases matter. Whether such `Floquet-Bloch' manipulation can be achieved in topological magnetic systems with disorder has so far been unclear. In this work, we realize Floquet-Bloch Dirac surface-state mass antiferromagnet (AFM) MnBi$_2$Te$_4$. Using time- and angle-resolved photoemission spectroscopy (tr-ARPES), show that opposite helicities mid-infrared circularly polarized light result...
