Effect of annealing on the temperature-dependent dielectric properties of LaAlO3 at terahertz frequencies

Effect of annealing on the temperature-dependent dielectric properties of LaAlO3 at terahertz frequencies

We present THz conductivity of LaAlO3 (LAO) as a function of temperature and annealing, using terahertz time-domain spectroscopy (THz-TDS). We observed that, after annealing, spectral weight redistribution occurs, such that the real conductivity σ1(ω) changed from a featureless and almost frequency-...
