Description

Controlling charge density waves (CDWs) in quantum materials enables the tuning of their electronic properties, offering potential for future electronic and optoelectronic applications. 1T-TaS$_2$ exhibits various temperature-dependent CDW phases, which we aim to modify through doping. We introduced molybdenum as a dopant during the crystal growth via the chemical vapor transport method. Using laser-based 11-eV ARPES, we investigated the differences in the electronic band structure between doped and pristine TaS$_2$ crystals. Our results demonstrate that different CDW phases persist at low doping concentrations, albeit with modified transition temperatures.
