14.1  INTRODUCTION

Single-electron transistor (SET) devices are of immense interest because of their potential for lowpower operation and high integration density. The basic building blocks of a SET device are tunnel junctions with very small capacitance that are connected in series with a central conducting island. Charge conduction occurs ...
