Abstract: The present application discloses a method for making and selecting a transcription enhancing combined promoter cassette, which includes constructing a library of randomly combined transcription regulatory elements, which comprise double stranded DNA sequence elements that are recognized by transcription regulators; inserting the combined transcription regulatory elements upstream of a minimum promoter followed by a reporter gene in a vector; inserting the vector into a host cell; and then screening for the cells showing enhanced expression of the reporter gene, and identifying the combined promoter cassette in the cell.

Abstract: Method for forming a Schottky contact in a semiconductor device includes a step of preparing an n type GaN group compound semiconductor layer, such as AlxGa1-xN and InxGa1-xN. At least one metal layer including a ruthenium component layer is formed on the n type GaN group compound semiconductor layer as a rectifying junction metal. The rectifying junction metal may be used as a gate of a field effect transistor, or an electrode of a Schottky diode. The ruthenium oxide has a low cost, is stable to heat and chemical, and has excellent electric characteristics. The application of the ruthenium oxide to the rectifying junction metal enhances performances, such as UV ray detection, of electronic devices and optical devices operable at an elevated temperature.
