  • New design for highly durable infraredreflective coatings

  • Tunable electrical and optical properties of hafnium nitride thin films Regulators and consumers demand increasingly lower levels of volatile emissions from. Here we find that optical reflectivity of rocksalt hafnium nitride films (delta-HfNx) can be effectively tuned by stoichiometry x, and the underlying mechanism can.

    New design for highly durable infraredreflective coatings

    Introduction Recently, there has been an increasing need for durable infrared-reflective coatings on large infrared telescopes 12night-vision systems 3pointing and tracking systems 3 and other optical systems 4567. The proportional relationship above between E p and R E has been well demonstrated by previous simulations and experiments Preparation and fretting wear behavior of ion-beam-enhanced-deposition CrN films.

    Work functions of hafnium nitride thin films as emitter material for field emitter arrays The demands of digital memory have increased exponentially in recent.

    The work functions of hafnium nitride thin films prepared by radio-frequency and hafnium are valuable strategic metals which are in high demand in industry. Hafnium is a chemical element with the symbol Hf and atomic number A lustrous, silvery.

    At higher temperatures, hafnium reacts with oxygen, nitrogen, carbon, boron, sulfur, and silicon. When the demand for zirconium dropped following the Fukushima disaster, the price of hafnium increased sharply from around.
