About

Koichi Maezawa was born in 1959 in Tokyo, Japan. He received a B.E. degree in applied physics, an M.S. degree in physics, and a Ph.D. degree in applied physics from Waseda University, Tokyo, Japan, in 1982, 1984, and 1993, respectively.

He was involved in the research and development of heterostructure FETs and quantum effect devices at NTT from 1984 to 1997, Nagoya University from 1997 to 2006, and University of Toyama from 2006 to 2024. He is currently President of Hokuriku Polytechnic College and Professor Emeritus of University of Toyama.

His current interests include heterostructure FETs, resonant tunneling devices, and applications of quantum functional devices to sensors.

Dr Maezawa is a member of the Japan Society of Applied Physics, the Physical Society of Japan, a senior member of the Institute of Electronics, Information and Communication Engineers of Japan, and a life senior member of the IEEE.

Metrics description
h-index
A scientist has an h-index if h of his N publications are cited at least h times each, while the remaining (N - h) publications are cited no more than h times each.
i10-index
The number of the author's publications that received at least 10 links each.
m-index
The researcher's m-index is numerically equal to the ratio of his h-index to the number of years that have passed since the first publication.
o-index
The geometric mean of the h-index and the number of citations of the most cited article of the scientist.
g-index
For a given set of articles, sorted in descending order of the number of citations that these articles received, the g-index is the largest number such that the g most cited articles received (in total) at least g2 citations.
w-index
If w articles of a researcher have at least 10w citations each and other publications are less than 10(w+1) citations, then the researcher's w-index is equal to w.
