Speech Title: Semiconductor Based Magnetoresistance and Magnetic Logic
Abstract- We developed a silicon based magnetoresistance (MR) device which combines the nonlinear property of diode and Hall Effect of semiconductor. The device can achieve a large MR at a few tens mT. We further developed a silicon based magnetic logic device which can do four Boolean logic functions of AND, OR, NAND and NOR. As all these pure silicon devices have a disadvantage that they cannot work at low magnetic field of ~mT, we propose an alternative route to improve MR performance by coupling nonlinear transport effect of semiconductor and anomalous Hall effect of magnetic material of CoFeB in one device. This device has MR of >20000 % with ~1 mT, the largest MR value at low magnetic field of mT.
We further proposed a magnetic logic-memory device by coupling anomalous Hall Effect in magnetic material and negative differential resistance phenomena in semiconductor. All four basic Boolean logic operations could be programmed by magnetic bit at room temperature with high output ratio (> 1000 %) and low magnetic field (~5 mT). This device demonstrated that non-volatile information reading, processing and writing could be realized in one step and one device. Hence, logic and non-volatile memory could be closely integrated in one chip. The time and energy used in the processes of information transformation and transfer could be saved. Moreover, this device was comparable with the function of neuron cell in brain that also combined memory and information process in one unit. A network with these highly parallel logic-memory devices could perform massively parallel non-volatile computing and might offer a possible route to approach brain-like artificial intelligence beyond traditional CMOS route.
