Tailoring of Bandgap and Spin-Orbit Splitting in ZrSe2 with Low Substitution of Ti for Zr
文献摘要：
Tuning the bandgap in layered transition metal dichalcogenides(TMDCs)is crucial for their versatile applications in many fields.The ternary formation is a viable method to tune the bandgap as well as other intrinsic prop-erties of TMDCs,because the multi-elemental characteristics provide additional tunability at the atomic level and advantageously alter the physical properties of TMDCs.Herein,ternary TixZr1-xSe2 single crystals were synthesized using the chemical-vapor-transport method.The changes in electronic structures of ZrSe2 induced by Ti substitution were revealed using angle-resolved photoemission spectroscopy.Our data show that at a low level of Ti substitution,the bandgap of TixZr1-xSe2 decreases monotonically,and the electronic system undergoes a transition from a semiconducting to a metallic state without a significant variation of dispersions of valence bands.Meanwhile,the size of spin-orbit splitting dominated by Se 4p orbitals decreases with the increase of Ti doping.Our work shows a convenient way to alter the bandgap and spin-orbit coupling in TMDCs at the low level of substitution of transition metals.
