Fig. 1 and 2 Schematic of ET-QW InAs MOSFETs and TEM images for L g = 50 nm ET-QW InAs MOSFETs with T QW = 5 nm. Note that 3-nm Al 2 O 3 was used as a gate insulator, together with MBE-grown 2-nm InP, leading to EOT = 2 nm. This paper reports Extremely-Thin-Body (ETB) InAs quantum-well (QW) MOSFETs with improved electrostatics down to L g = 50 nm (S =103(More)
Crab cavities have been installed in the KEKB B– Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab crossing has been done since February 2007. This is the first experience with such cavities in colliders or storage rings. The crab cavities have been working without serious(More)

(a) The proposed hitting using t = t 1d and = tan 01 k: (b) A conventional hitting with t = t 1 and = 0: be driven slantwise by the friction force on the face of the nail head. First, the normal of the board is directed with 8 8 8 X = 90 and 8 8 8 Z = 30 , and a nail is tapped perpendicularly on the(More)
