1. INTRODUCTION

Over the past three decades there has been increased interest in the study of thin-film nano-structures for chemical sensors based on nanobelts, nanowires, and nanotubes. These nano-structures have a great potential to revolutionize chemical and environmental sensors. Three-terminal field-effect transistors (FETs) are certainly staking their share in this area, as evidenced by the rapidly-growing number of articles published on novel nanostructure sensors with ...
