Stanene is a
topological insulator, theoretically predicted by Prof. Shoucheng Zhang's group at Stanford, which may display dissipationless currents at its edges near
room temperature
Colloquially, "room temperature" is a range of air temperatures that most people prefer for indoor settings. It feels comfortable to a person when they are wearing typical indoor clothing. Human comfort can extend beyond this range depending on ...
. It is composed of
tin atoms arranged in a single layer, in a manner similar to
graphene. Stanene got its name by combining ''stannum'' (the
Latin name for tin) with the
suffix
In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns, adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carry ...
''
-ene
The suffix -ene is used in organic chemistry to form names of organic compounds where the -C=C- group has been attributed the highest priority according to the rules of organic nomenclature. Sometimes a number between hyphens is inserted before i ...
