The present invention describes a transistor based on a Hetero junction FET structure, where the metal gate has been replaced by a stack formed by a highly doped compound semiconductor and an insulating layer in order to achieve enhancement mode operation and at the same time drastically reduce the gate current leakage. The combination of the insulating layer with a highly doped semiconductor allows the tuning of the threshold voltage of the device at the desired value by simply changing the composition of the semiconductor layer forming the gate region and/or its doping allowing a higher degree of freedom. In one of the embodiment, a back-barrier layer and a heavily doped threshold tuning layer are used to suppress Short Channel Effect phenomena and to adjust the threshold voltage of the device at the desired value. The present invention can be realized both with polar and non-polar (or semi-polar) materials.

The invention provides a water treatment technology for controlling bromate generation on the basis of graphene-based material adsorption/catalytic oxidation cascade coupling. Bromate treatment unitsmainly related in the technology are a sulfur-doped graphene (S-rGO) adsorption bromide ion unit, a graphene (rGO) catalytic oxidation unit and a S-rGO adsorption bromate unit, wherein S-rGO has highadsorption performance for bromide ions and bromate, and rGO not only has the excellent catalytic oxidation performance but also has the capacity of controlling bromate. Accordingly, different runningtechnologies and methods can be made according to the concentrations of different water sources, bromate generation in the advanced oxidation process is controlled easily. The technology can be applied to the drinking water deep treatment aspect, operation is easy, and implementation is easy.

The invention provides a method and terminal for operating a web browser with a remote controller. The method comprises the following steps: receiving a command for entering a cursor mode, and settingthe system status to be cursor mode; receiving a key value transmitted by the remote controller, and controlling the cursor to actuate corresponding operation on the web browser according to the keyvalue, including moving and clicking; and switching the remote controller to a cursor operation mode when browsing a webpage, and moving the cursor to an arbitrary menu and link on the webpage for visiting. The method is simple and convenient to operate, and does not need re-compiling.
