(Or "quaNTum dot cell") A structure comprising four quaNTum dots arranged in a square, with two diagonally opposed dots coNTaining electron charges. One diagonal coNTaining charges is arbitrarily defined as represeNTing a value of ' 1' , the other as ' 0' . In a five-dot cell, the fifth, ceNTral dot coNTains no charge. See also: quaNTum cell wire, quaNTum-dot cellular automata. . ["QuaNTum Dot Heterostructures", D. Bimberg, et al, John Wiley & Sons Ltd., Dec 1998]. [ImplemeNTations?] (2001-07-17)
