Electromagnetic wave detection methods and apparatus |
摘要 |
Methods and apparatus for detecting an electromagnetic wave are provided. A device for use in an electromagnetic wave detector includes a first device layer having a first contact, a second device layer having a second contact, and a tunnel barrier layer and a resonating magnetic layer formed between the first and second device layers. The resonating magnetic layer produces a spin current responsive to an electromagnetic wave that extends into the first and second device layers. A charge differential present between the first and second contacts is dependent on the spin current. |
