We make small devices with techniques of electron beam lithography.
Followings are scanning electron micrographs of our devices.
Quad quantum dot ver. 2I am inspired by a four-leaf clover.
Quad quantum dotIt becomes complicated.
Large quantum point contact
Device for charge deterction with quantum point contact ver. 2We made the gaps wider.
Device for charge deterction with quantum point contactGaps between the gates are too small to survive in a season of static electricity.
Circular simple quantum dot
Double side-coupled quantum dot ver. 2The size is smaller.
