Abstract: Currently, as next - generation MOS devices, a highk/Ge structure, which has high electron and hole mobility than that of Si, and has the ability to low power consumption during device operation has been expected. Although HfO2 which exhibits excellent characteristics on silicon can be applied as high-k material, it is known that Ge and HfO2 cause diffusion of atoms due to heat treatment during device fabrication process and deteriorate electric characteristics such as large leakage current in HfO2 film and large interface trap density at the HfO2/Ge interface. Therefore, lower fabrication process temperature has been attempted by introducing Kr/O2 plasma oxidation instead of conventional thermal oxidation method in this research. As a result, compared to thermal oxidation, the leakage current is greatly reduced and the electrical characteristics are drastically improved by using Kr/O2 plasma oxidation. Therefore, we can conclude that high quality HfO2 can be formed on Ge substrates, a

Abstract: Freelancing is doing a job under contract rather than full employment. Usually, people who freelance are selfemployed and for whom they will work and they decide for how long. Freelancing offers the lot of freedom and flexibility which regular jobs cannot. The freelancer can choose the type of the work, time of the day can work and how long they work, a location they work and volume of work take on. The freelancer can control work relationship and control workload. Platform freelancing has many websites and anyone can register as freelancers or job posters. Sri Lankan service providers register as freelancers through these websites. there is no local freelancing platform for Sri Lankan freelancers yet. They register through foreign freelancing platforms. A major issue of these systems is Sri Lankan freelancers cannot get gross profit for their services. Foreign freelancing sites charge a higher percentage of their revenue as service charges. The system is developed to overcome these dr
