Figure Lengend Snippet: Characterization of Bi 2 Te 3 single crystals and the device fabrication process. (a) Left panel: Digital images represent the Bi 2 Te 3 single crystals; Right panel: SEM and EDX images acquired from the surface of the exfoliated Bi 2 Te 3, indicating a smooth morphology and uniform elemental composition. (b) XRD pattern of Bi 2 Te 3 transferred onto PET substrates, showing only (00 l ) family of planes, confirming the single‐crystal nature. (c) Stepwise schematic of the Bi 2 Te 3 transfer process using a PDMS stamp, presenting the stacking of thin film onto pre‐patterned Au electrodes to form the planar memristor architecture. (d) SEM image of the as‐transferred Bi 2 Te 3 indicates the successful bridging between Au electrodes with clean interfacial contact. (e) AFM height map of the Bi 2 Te 3 surface shows a clean and featureless morphology. The inset presents a step‐like height profile, ensuring the layered structure.
