Cr1+dTe2 is a self-intercalated transition metal dichalcogenide that hoststunable electronic filling and magnetism in its semimetallic band structure.Recent angle-resolved photoemission spectroscopy (ARPES) studies have unveileda systematic shift in this semimetallic band structure relative to the chemicalpotential with increased Cr doping. This report presents the temperature andmagnetic field dependence of the longitudinal thermopower Sxx for differentCr1+dTe2 compositions. We show that as doping increases, the sign of Sxxchanges from positive to negative at the critical doping level of d ~ 0.5. Thisobserved doping-dependent trend in the thermopower is consistent with theevolution of the semimetallic band structure from ARPES. Importantly, ananomalous enhancement of the thermoelectric response is also observed aroundd~0.5. Combining information from magnetometry and ARPES measurements,existence of the critical nature of the doping level dc (~0.5) is unveiled inmagnetic semimetal Cr1+dTe2, where antiferromagnetic fluctuation andnear-Fermi-energy pseudogap formation play a potential vital role in enhancingthermoelectric energy conversion.
