Dear Editors, Tungsten ditelluride (WTe 2) is a layered transition-metal dichalcogenide (TMD). The tungsten layers are clipped by the adjacent chalcogenide layers. The sandwich structure stacks along the c-axis with Van Der Waals bonding between layers. Particularly, are formed along the a-axis within the dichalcogenide layers .WTe_2 has attracted tremendous attention [1-3] owing to its extremely large
