Title:
QUANTUM DEVICE, METHOD FOR CONTROLLING SUCH QUANTUM DEVICE AND METHOD FOR MANUFACTURING SUCH QUANTUM DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/097976
Kind Code:
A1
Abstract:
A quantum dot (22) is formed on a GaAs substrate (20). In the quantum dot (22), a single electron exists. A cap layer (26) is formed on a circumference of the quantum dot (22), and a barrier layer (28) is formed on the cap layer. A quantum dot (30) for detection is formed on the barrier layer (28). Then, a cap layer (34) is formed to cover the quantum dot (30) and the like.
