Evidence for a Self-Bound Liquid State and the Commensurate-Incommensurate Coexistence in 2D ${}^3$He on Graphite

D. Sato, D. Tsuji, S. Takayoshi +3

We made heat-capacity measurements of two dimensional (2D) ${}^3$He adsorbed on graphite preplated with monolayer ${}^4$He in a wide temperature range (0.1 $\le T\le$ 80 mK) at dens…
