Semiconductor substrate, method for producing semiconductor substrate, substrate for semiconductor growth, method for producing substrate for semiconductor growth, semiconductor element, light-emitting element, display panel, electronic element, solar cell element, and electronic device

A method of producing a semiconductor substrate comprising causing a semiconductor layer to grow on a surface of a graphite layer that forms a surface of a substrate, the graphite layer being formed of a benzimidazobenzophenanthroline ladder polymer or a binaphthyltetracarboxylic acid-biphenyltetramine polymer.

A method of producing a semiconductor substrate comprising causing a buffer layer to grow on a surface of a graphite layer that forms a surface of a substrate, and causing a semiconductor layer to grow on a surface of the buffer layer, the graphite layer being formed of a benzimidazobenzophenanthroline ladder polymer or a binaphthyltetracarboxylic acid-biphenyltetramine polymer.

A semiconductor growth substrate comprising a graphite layer that forms a surface of the semiconductor growth substrate, the graphite layer being formed of a benzimidazobenzophenanthroline ladder polymer or a binaphthyltetracarboxylic acid-biphenyltetramine polymer.

A method of producing a semiconductor growth substrate comprising forming a graphite layer on a base, the graphite layer being formed of a benzimidazobenzophenanthroline ladder polymer or a binaphthyltetracarboxylic acid-biphenyltetramine polymer, and the base being formed of an organic compound that differs from the benzimidazobenzophenanthroline ladder polymer or the binaphthyltetracarboxylic acid-biphenyltetramine polymer, respectively.

A method of producing a semiconductor growth substrate comprising forming a layer of a benzimidazobenzophenanthroline ladder polymer or a binaphthyltetracarboxylic acid-biphenyltetramine polymer on a free-standing base, and separating the layer of the respective benzimidazobenzophenanthroline ladder polymer or binaphthyltetracarboxylic acid-biphenyltetramine polymer from the free-standing base to obtain a graphite layer.
