Our work shows that the thermal conductivityκof MoS2is largest among the three materials (Fig. a and b) due to largest Debye temperature. WS2has stronger bonding (Fig. e) and lower anharmonicity (Fig. h), leading to a much largerκcompared to MoSe2.

A fundamental understanding of phonon transport in stanene is crucial to predict the thermal performance in potential stanene-based devices. By combining first-principle calculation and phonon Boltzmann transport equation, we obtain the lattice thermal conductivity of stanene. A much lower thermal conductivity (11.6 W/mK) is observed in stanene, which indicates higher thermoelectric efficiency over other 2D materials. The contributions of acoustic and optical phonons to the lattice thermal conductivity are evaluated. Detailed analysis of phase space for three-phonon processes shows that phonon scattering channels LA + LA/TA/ZA ↔ TA/ZA are restricted, leading to the dominant contributions of high-group-velocity LA phonons to the thermal conductivity. The size dependence of thermal conductivity is investigated as well for the purpose of the design of thermoelectric nanostructures.

Accurate in situ measurement of complex optical surfaces is desired for precision manufacturing, and deflectometry is a promising measuring method. However, deflectometry’s measurement accuracy depends heavily on the geometric calibration’s reliability. Existing calibration methods suffer from the limitations of low efficiency, complicated operations, and expensive equipment. Therefore, a self-calibration method is proposed for the monoscopic deflectometry in order to determine the the camera and screen positions. A flat mirror without markers, rather than high-precision metrological instruments, is employed to assist with the self-calibration work, and a re-projection model is adopted in order to trace the rays from the screen to the camera. Numerical optimization is performed on the global parameters—including the camera intrinsic parameters, the screen intrinsic parameters, and the geometric transformations—in order to improve the geometric calibration’s reliability. This self-calibration method only requires that four images be captured, hereby reducing the operating complexity and improving the measuring efficiency. Experiments demonstrate that the re-projection error can be significantly decreased, and also that the measuring accuracy of specular surfaces is comparable to high-precision interferometry.

At room temperature, the uniaxial strain ( ε x = −8%) can enhance the hole mobility of monolayer penta-SiC2 along the b -direction by almost three orders of magnitude up to 1.14 × 10 6 cm 2 V −1 s −1 , which is much larger than that of graphene.
