Fig. 3: The partial density of states (PDOS) of TiS2 and MoS2 within TiS2(ML to 4L)–MoS2(ML) contacts.
From: Titanium disulfide as Schottky/ohmic contact for monolayer molybdenum disulfide
a–d PDOS of TiS2 (from ML to 4L). In the plot, the dashed line indicates the position of Fermi level, which is set as zero point. The red line represents the DOS of free-standing TiS2, as a comparison. e–i PDOS of ML MoS2. On the top is the DOS of free-standing ML MoS2, as a comparison. The Fermi level of each plot has been aligned to the same energy value. The label ML-TiS2 to 4L-TiS2 indicate the TiS2 contact thickness.
