The engineered substrate also includes an bonding layer coupled to the support structure, a substantially single crystal layer coupled to the bonding layer, and an epitaxial gallium nitride layer coupled to the substantially single crystal layer.

A plate-shaped heat dissipation member includes a metal-silicon carbide composite containing aluminum or magnesium, in which at least one of two main surfaces of the heat dissipation member is curved to be convex in an outward direction of the heat dissipation member, and when a flatness of the one main surface defined by JIS B 0621 is represented by f.sub.1 and a flatness of the other main surface different from the one main surface defined by JIS B 0621 is represented by f.sub.2, f.sub.2 is less than f.sub.1 by 10 m or more.

Multilayer substrates for the growth and/or support of CNT arrays are provided. These multilayer substrates both promote the growth of dense vertically aligned CNT arrays and provide excellent adhesion between the CNTs and metal surfaces. Carbon nanotube arrays formed using multilayer substrates, which exhibit high thermal conductivity and excellent durability, are also provided. These arrays can be used as thermal interface materials.

The invention relates to a flat steel product, which is intended to be formed into a component by hot press forming and has a base made of steel, onto which a metal anti-corrosion coating is applied, which is formed by Zn or a Zn alloy. This is achieved as per the invention in that a separate finishing coat is applied to at least one of the free surfaces of the flat steel product which contains at least one base metal compound (oxide, nitride, sulphide, sulphate, carbide, carbonate, fluoride, hydrate, hydroxide, or phosphate). Furthermore the invention relates to a method enabling the production of a flat steel product of this kind.
