Abstract
Source-gated transistors (SGTs) have been made in thin layers of polysilicon formed by excimer laser crystallization of amorphous silicon. It is shown that the main features of the SGT, namely a low saturation voltage and high output impedance can be obtained in poly-silicon. Furthermore the nature of the source barrier enabled it to be pulled down by the influence of the gate to low values giving small activation energies for current transport and reduced temperature sensitivity in the on-state.
