Carrier transport in continuous-wave laser lateral-crystallised (CLC) poly-Si thin film transistors (TFTs) has been investigated. Large Si grains formed by the laser crystallisation, enhanced electron mobility of the CLC poly-Si TFT. It was found that the effective electron mobility was free from grain boundary scattering and was mainly governed by phonon scattering; its variation, however, was governed by the number of grains in the channel region.
