Greetings,
TMDC mono-layer hetero junction I made by transferring of each flake (mono-layer attached with bulk portion) on gold contact fingers(bottom electrode contacts made on 300nm SiO2 substrate). Notable things is , stacked mono-layers form hetero junction. The bulk portions attached with mono-layers contacted on gold electrodes. This hetero junction is photosensitive (p - n photo diode ). The measured IV(photo IV) and transport characteristics showing unique results than all published works. Results showing, the formed hetero junction could lead to feasibility of the self biasing device(IR detector) as well. Which is unique than i ever read from published articles for my material. Thus, I got question, if the mono-layer connected with bulk together could show any different results , even though the hetero made with mono-layer portion only ?
I couldn't find any right paper which has been argued about these. Please, help me to resolve this question ?
Of-course the screening effect becomes stronger on bulk portion compare to mono-layer. I would need the scientific data which can resolve my question rather than technical one. I would be glad to get your valuable answers or comments
Eventually, I got the key answer
