Preface

Microelectronic devices contain multiple layers of dissimilar materials, including metals, dielectrics, and semiconductors. When integrating these heterogeneous materials to create a device, the boundary that separates each pair of materials is called their interface. Examples are dielectric-semiconductor interfaces, metalsemiconductor interfaces, and metal-dielectric interfaces. As the device structures in gigascale electronics continue to shrink, their functionality is not only affected by the film quality of these dissimilar materials, but also is more and more determined by the stability of their interfaces. Interface stability has become an increasingly important issue that has a profound impact on the reliability of electronic devices during operation. For instance, the dielectric-semiconductor interface, such as the SiO2–Si interface, was intensely studi
