Abstract: An AlGaN/GaN HEMT based on fluorinated graphene passivation and a manufacturing method thereof. Monolayer graphene (108) is transferred to an AlGaN (104) surface, is treated by using fluoride ions and then is insulated to thereby replace a conventional nitride passivation layer. Then, a high-k material (109) is grown on the graphene (108), and the high-k material (109) and the graphene (108) are jointly used as a gate dielectric for preparing an AlGaN/GaN metal-insulator-semiconductor (MIS) HEMT. Compared with the traditional passivation structure, the graphene (108) has the advantages of small physical thickness (sub-nanometer scale) and low additional threshold voltage. The structure and the method are simple, the effect is remarkable and the application prospect in technical fields of microelectronics and solid-state electronics is wide.

The separator is arranged between an oil drain pipe and an accident oil tank, and has a cylindrical structure, and includes an oil storage compartment, a water storage compartment and a partition plate between them. The disclosure can ensure that the accident oil tank is empty under normal operating conditions so that a platform weight is reduced; and an insulation and an electric heating treatments are only performed at the oil-water separator to save insulation project quantity and energy consumption for heating; and a two-stage oil-water separation is achieved in the oil-water separator to avoid mixing oil droplets into water discharged from a water outlet.

Abstract: A method of generating diffraction images based on wave equations includes generating a source wavefield and a receiver wavefield. Based on the source wavefield, a first source wavefield propagating in a first direction and a second source wavefield propagating in a second direction are generated. Based on the receiver wavefield, a first receiver wavefield propagating in the first direction and a second receiver wavefield propagating in the second direction are generated. A first seismic image is generated based on the first source wavefield and the first receiver wavefield. A second seismic image is generated based on the second source wavefield and the second receiver wavefield. A final seismic image is generated based on the first seismic image and the second seismic image.
