1.6 GaU-Pb zircon age for the Chorhat Sandstone, lower Vindhyan, India: Possible implications for early evolution of animals
(GEOLOGICAL SOC AMERICA, INC, 2002)Bedding-plane markings in the Chorhat Sandstone (lower Vindhyan), central India, were recently interpreted as burrows produced by triploblastic animals. Because the rocks were thought to be older than 1000 Ma, these ... -
1/f Noise in Drain and Gate Current of MOSFETs With High-k Gate Stacks
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)In this paper, we investigate the quality of MOSFET gate stacks where high-k materials are implemented as gate dielectrics. We evaluate both drain- and gate-current noises in order to obtain information about the defect ... -
