Strontium molybdate (SrMoO3) thin films are shown to exhibit plasmonic\nbehaviour with a zero crossover wavelength of the real part of the dielectric\npermittivity tunable between 600 and 950 nm (2.05 eV and 1.31 eV). The films\nare grown epitaxially on strontium titanate (SrTiO3), magnesium oxide (MgO),\nand lanthanum aluminate (LaAlO3) substrates by pulsed laser deposition. SrMoO3\nis shown to have optical losses lower than those of gold at the point at which\nthe real part of the dielectric permittivity is equal to -2, while possessing\nlow electrical resistivity of 100E-6 Ohm cm at room temperature. Spectroscopic\nellipsometry measurements reveal that SrMoO3 shows plasmonic behaviour,\nmoreover we demonstrate that the epsilon near zero (ENZ) wavelength is tunable\nby engineering the residual strain in the films. The relatively broadband ENZ\nbehaviour observed in SrMoO3 demonstrates its potential suitability for\ntransformation optics along with plasmonic applications in the visible to near\ninfrared spectral range.\n
