This book focuses on the photoelectric nanodevices based on carbon nanostructures, such as carbon nanotubes, graphene and related heterojunctions. The synthesis of carbon nanostructures and device fabrication are simply given. The interface charge transfer and the performance enhancement in the photodetectors and solar cells are comprehensively introduced. Importantly, carbon allotropes behave as high-mobility conductors or bandgap-tunable semiconductors depending on the atomic arrangement...

Over the past several decades, researchers as well as social policymakers and educators have acknowledged the importance that fathers play in their children's lives. A good deal of research on fathering has been conducted among Euro-American families in North America. However, our understanding of fathering across various ethnic groups remains limited. Throughout Canada and the United States, the immigrant population has been growing rapidly. Currently, no book has delineated the field of ...
