Abstract: A drill structure comprises a shank part and a bit part. A web is formed on the front end of the bit part. Two sides of the web are tilted backward to form two cutting faces. At least one chip-discharge groove is formed on the surface of the bit part. Each cutting face includes a primary cutting face and a secondary cutting face. The thickness of the prismatic web edge of at least one primary cutting face is smaller than the outer-side width of the primary cutting face. An auxiliary cutting face is extended to the wall of the flute from the cutting edge of the primary cutting face and a portion of a blade back of the secondary cutting face of another cutting face. The present invention decreases the drilling resistance during drilling a hole and increases the service life of the drill bit.

Abstract: Devices converting light to electricity (such as solar cells or photodetectors) including a heavily-doped p-type a-SiCy:H and an i-MgxCd1-xTe/n-CdTe/N—Mg0.24Cd0.76Te double heterostructure (DH), with power conversion efficiency of as high as 17%, Voc as high as 1.096 V, and all operational characteristics being substantially better than those of monocrystalline solar cells known to-date. The a-SiCy:H layer is configured to enable high built-in potential while, at the same time, allowing the doped absorber to maintain a very long carry lifetime. In comparison, similar undoped CdTe/MgxCd1-xTe DH designs reveal a long carrier lifetime of 3.6 ?s and an interface recommendation velocity of 1.2 cm/s, which are lower than the record values reported for GaAs/Al0.5Ga0.5As (18 cm/s) and GaAs/Ga0.5In0.5P (1.5 cm/s) DHs.
