Strongly Enhanced Charge-Density Waves and Correlated Insulating State in Atomically Thin 1T-TaS_{2}

{{output}}
We investigate thickness-dependent charge-density-wave (CDW) transitions in 1T-TaS_{2} using temperature-dependent Raman spectroscopy and electrical transport. Raman measurements show that the incommensurate, nearly commensurate, and commensurate CDW phases pe... ...
