In this work, we used isothermal close space (ICS) Te annealings in pure H2 atmosphere for the tellurization of Mo oxide thin films. Differently to previous open tube tellurization annealings, ICS is expected to provide a higher Te vapor pressure bec

We report the linear and nonlinear optical properties of single GaAs nanowires with polytypism effect. Electron transmission microscopy experiments show that the nanowires contain wurtzite segments as well as zinc blende segments with two different c

Exciton polariton is a quasi-particle formed in a microcavity, which keeps the exciton and the photon property, e.g. the exciton longitudinal–transversal energy splitting. In this work we observed a splitting as large as 0.19 meV in the polariton e

In this paper we identify experimentally an unstable polariton laser emission through cavity spontaneous self-oscillations when excited resonantly in continuous mode. The experimental results indicate the coexistence of a laser state (in a non-conden
