The authors show that carbon nanotubes ͑CNTs͒ coated with an amorphous silicon layer around their periphery show enhanced and stable electron emission. The CNT-field emitter array was grown on silicon substrate through a resist-assisted patterning process. The CNTs become coated with silicon from the substrate, which is etched and redeposited onto the CNTs. The authors obtained enhanced and stabilized electron emission from the silicon coated CNTs with a turn-on field of 2 V/ m at an emission current density of 1 A / cm 2 . The structure and electron emission properties of the functionalized emitters are discussed.

The integration of carbon nanotube (CNT) emitters with metaloxide-semiconductor field-effect transistor (MOSFET) can stabilize and control the emission current of carbon nanotubes (CNTs). As the unit process, the CNTs were grown on the drain part of MOSFETs using the resist-assisted patterning (RAP) process. The electron emission current of CNTs grown on the drain was switched with a low voltage of the externally connected field-effect transistor and was uniform. The electron emission properties of CNT-emitters with the externally connected fieldeffect transistor were discussed.

Because the increased number of Internet users and the common use of IT technology via the expansion of domestic IT infrastructure have increased the web site use of companies, Internet users have begun to experience a range of online websites. In a digital environment, entrepreneurial companies who have limited resources will require effective management by analyzing the critical factors of the website quality assessment and focusing their resources to seize the market because the website quality built in the company directly affects the satisfaction and purchase activity of the customers. In this study, a total of 523 surveys from the customers visiting online websites of the entrepreneurial companies were collected to analyze the factors between the influencing factors and satisfaction and purchase intention using the ServQual method in the AMOS 18.0 program. This analysis showed that the customers visiting the website are satisfied with the factors of tangibility, reliability and responsiveness of visited websites, and the factor of community, which indicates that the level of customer activity in the web sites is related significantly to the customers' purchase intentions.
