The attraction between electrons and holes in semiconductors forms excitons, which largely determine the optical properties of the hosting material, and hence the device performance, especially for low-dimensional systems. Mono- and few-layer black phosphorus (BP) are emerging two-dimensional (2D) semiconductors. Despite its fundamental importance and technological interest, experimental invest...

Existing studies on broadband adoption have investigated how behavioural and demographic factors affect consumers’ decision to adopt broadband. However, although the broadband market has been considerably matured, follow up studies on the continued adoption of broadband are yet to be conducted. For example issues of service quality and consumers satisfaction of broadband services have not been ...

1. Introduction By any measure, the communication sector is important. The combined revenues of the U.S. telephone and postal industries are larger than military spending for that country, and almost three times higher than the revenues of the airline industry. (Table 1, taken from Odlyzko (2000), gives further comparisons.) The sector has been expanding for many centuries. The postal service a...
