High-Frequency Spin-Based Devices for Nanoscale Signal Processing
Abstract
This seedling project continues to focus on developing and demonstrating key improvements that are needed for successful application of spin-based devices in nanoscale high-frequency signal processors, on chip microwave spectroscopy, and active smart materials. The devices one which we have concentrated effort are spin-transfer nano-oscillators (STNOs) and spin torque diodes (STDs). STNOs and STDs offer advantages over existing voltage controlled oscillators/ mixers/detectors including a small form factor (100 nm for a single device, < 100 um for a 1000 element array), wide tunability range, low power, low capacitance (1 fF), insensitivity to temperature, radiation hardness, integrability with CMOS, and integrability with a wide range of traditional and nontraditional substrates. The advances needed to bring this technology to a level of maturity for practical applications in spectroscopy and signal processing include: increasing STNO power output above 1 uW (with linewidths below 20 MHz), improving STD sensitivity to > 100 V/W, demonstration of operation at frequencies >/_ 100 GHz, demonstration of phase coherent STNO arrays, and coupling STNOs and STDs to compact, planar antennas.
