    100% Accuracy in Automatic Face Recognition

    National security and crime prevention often depend on ability to establish the identities of individuals and check that they are whom they claim to be. This proof of identity is frequently achieved by comparing the individual's appearance to a photo-identification document such as a passport. Although there are now a...

    Ambipolar Pentacene Field-Effect Transistors and Inverters

    Organic field-effect transistors based on pentacene single crystals, prepared with an amorphous aluminum oxide gate insulator, are capable of ambipolar operation and can be used for the preparation of complementary inverter circuits. The field-effect mobilities of carriers in these transistors increase from 2.7 and 1.7 square centimeters per volt per...
