英文摘要Phase-structure diversity affords tungsten thin films with fascinating physical/chemical properties for varied applications. However, the on-demand preparation of W films with specific phase is still an important but unmet scientific issue. In this report, an easy-to-achieve preparation recipe is implemented for addressing the phase tailoring of tungsten films. The phase transformation evolution during deposition is governed by enhanced diffusion of W adatoms and selective atomic etching on the crystal planes. It is experimentally demonstrated that the orientation relation between {210}(beta) and {110}(alpha) planes plays a vital role in coupling with the competitive growth behaviors between beta- and alpha-W. The phase-dependent electrical/optical properties of W films are experimentally observed and unambiguously figured out by theoretical simulations. Alpha-phase-dominated W films are prepared successfully under relatively tolerant conditions, demonstrating a low resistivity of approximate to 13.6 mu omega cm and a high infrared reflectance larger than 93%. Alpha-W also serves as thermal reflector to construct a solar absorber, exhibiting a low thermal emissivity of approximate to 9.8%@500 degrees C. Understanding the (alpha, beta) phase transformation mechanism means a big step forward in the development of the on-demand preparation, which allows to build a scalable platform for making W films with specific phase in a more controllable way.
