“…Hawking processing, a new technology of USRP, uses the combination of high frequency mechanical energy and thermal energy to grind metallic surface by the cold plastic deformation and then improves material surface quality [14]. Compared with conventional mechanical working, hawking processing can decrease the surface roughness to 0.1μm, increase the fatigue life by dozens of times, the surface hardness by more than 20%, the corrosion resistance by more than 40% and the wear resistance by more than 50% [15].Researches showed that the lower the feed and the static load are, the smaller the surface roughness of the treated specimen is [16].…”

S30408 austenitic stainless steel was treated by using hawking processing which is a type of ultrasonic surface rolling process (USRP). The effects of USRP parameters on surface roughness, surface hardness and corrosion resistance were investigated. Compared with the untreated specimen, the surface roughness and surface hardness is decreased by 87%, the surface hardness is increased by 51% and the corrosion rate reduces after USRP. The surface roughness decreases obviously as the step-size decreases, while the step-size has little effect on the surface hardness and corrosion resistance.

Nano air channel transistors (NACTs) provide numerous advantages over traditional silicon devices, including faster switching speeds, higher operating frequencies, and enhanced radiation hardness attributable to the ballistic transport of electrons. In the development of field‐emission‐based integrated circuits, low‐power consumption rectifying nano air channel diodes (NACDs) play a crucial role. However, achieving rectification characteristics in NACDs is challenging due to their structural and material symmetry. This paper proposes a vertical GaN NACD with a consistent nano air channel fabricated using IC‐compatible processes. The GaN NACD exhibits an exceptionally low turn‐on voltage of 0.3 V while delivering a high output current of 5.02 mA at 3 V. Notably, it demonstrates a high rectification ratio of up to 2.2 × 105, attributing to significant work function disparities within the GaN‐Au structure, coupled with the reduction of Au surface roughness to minimize reverse current. Furthermore, the junction‐free structure and superior material properties of GaN enable the NACD to be suitable for use in radiation‐rich environments. With its potential as a fundamental component of ultrafast and ultrahigh‐frequency integrated circuits, this intriguing and cost‐effective rectifying diode is anticipated to garner widespread interest within the electronics community.
