58.1  INTRODUCTION

Although polysilicon thin-film transistors (poly-Si TFTs) are attracting much attention for their use in active-matrix liquid crystal displays [1,2], fine-grain structures in the channel can affect their carrier transport and device performance. Poly-Si consists of a number of single-crystal grains. Between poly-Si grains, there exists a high defect density region called the grain boundary with a typical value of defect density ca. 1012 cm−2. Such a large number ...
