Abstract
In this letter, the low-frequency noise performance of single-halo (SH) devices is reported, and the physical mechanisms are identified. Experimental results show that, at constant gate overdrive voltages, SH devices show reduced low-frequency noise levels compared to the conventional devices. However, under constant current bias conditions, the noise reduction is less substantial. Low-frequency noise dependence on channel length is also investigated for SH devices based on the electrical measurements and analytical calculations
