Direct measurement of ferroelectric polarization in a tunable semimetal

Direct measurement of ferroelectric polarization in a tunable semimetal

Free carriers and electrical polarization coexist in ferroelectric metals. Here, the authors use a capacitive method to probe the electronic compressibility of free carriers in a tunable semimetal, extract the polarized contribution, and study the carrier dependence of the ferroelectric state.
