Despite the sizable interlayer separation and metallic nature of the1H layer, positive bias voltages result in a pronounced superposition of the1T charge density wave structure on the 1H layer. The conventional explanation relying on tunneling effects proves insufficient. Through a comprehensive investigation combining low-temperature scanning tunneling microscopy, scanning tunneling spectroscopy, non-contact atomic force microscopy, and first-principles calculations, we propose an alternative interpretation.The transparency effect arises from a weak yet substantial electronic coupling between the 1H and 1T layers,challenging prior understanding of the system. Our results highlight the critical role played by interlayer electronic interactions in van der Waals<br \/>\nheterostructures to determine the final ground states of the systems.
