    摘要: An apparatus including a crucible, an energy source, and a controller is provided. The crucible may be sealed to a nitrogen-containing gas, and may be chemically inert to at least ammonia at a temperature in a range of about 400 degrees Celsius to about 2500 degrees Celsius. The energy source may supply thermal energy to the crucible. The controller may control the energy source to selectively direct sufficient thermal energy to a predefined first volume within the crucible to attain and maintain a temperature in the first volume to be in a range of from about 400 degrees Celsius to about 2500 degrees Celsius. The thermal energy may be sufficient to initiate, sustain, or both initiate and sustain growth of a crystal in the first volume. The first temperature in the first volume may be controllable separately from a second temperature in another volume within the crucible. The first temperature and the second temperature differ from each other. Associated methods are provided.

    摘要: A composition including a polycrystalline metal nitride having a number of grains is provided. These grains have a columnar structure with one or more properties such as, an average grain size, a tilt angle, an impurity content, a porosity, a density, and an atomic fraction of the metal in the metal nitride. An apparatus for preparing a metal nitride is provided. The apparatus may include a housing having an interior surface that defines a chamber and an energy source to supply energy to the chamber. A first inlet may be provided to flow a nitrogen-containing gas into the chamber. Raw materials may be introduced into the chamber through a raw material inlet. A second inlet may be provided to flow in a halide-containing gas in the chamber. The apparatus may further include a controller, which communicates with the various components of the apparatus such as, sensors, valves, and energy source, and may optimize and control the reaction.
