# Mitsutaka Fujita

Mitsutaka Fujita (藤田 光孝, Fujita Mitsutaka, August 16, 1959 – March 18, 1998) was a Japanese physicist. He proposed the edge state that is unique to graphene zigzag edges. Also, he theoretically pointed out the importance and peculiarity of nanoscale and edge shape effects in nanographene. The theoretical concept of graphene nanoribbons was introduced by him and his research group to study the nanoscale effect of graphene. He was an associate professor at Tsukuba University, and died of a subarachnoid hemorrhage on March 18, 1998. His posthumous name is Rikakuin-Shinju-Houkou-Koji (理覚院深珠放光居士) in Japanese.

## Awards

After his death, the original paper on graphene edge state and graphene nanoribbons was awarded the JPS Best Paper Award in March 2003 from the Physical Society of Japan.
