Atomic Layer Deposition of TiO₂ on MoTe₂: Chemical Changes, Band Offsets, and Photophysics.

ABSTRACT: Transition metal dichalcogenides (TMDCs) are well suited to optoelectronic applications due to their strong absorption of a broad spectrum of wavelengths and their layered structure, which permits the assembly of van der Waals heterostructures. The behavior of TMDC-TMO (transition metal oxide) interfaces is an important topic for the potential development of TMDC-based optoelectronics, as they may be effective either as active components of optoelectronic devices or as interlayers between TMDCs and metals, improving contact efficiencies. Here, TiO₂-MoTe₂ junctions were studied to determine the effectiveness of TiO₂ synthesized with atomic layer deposition (ALD) as a potential charge-separating layer for MoTe₂. Band alignments measured with X-ray
