ABSTRACT: This paper presents a chronological overview of Korean activities in optoelectronics and optoelectronic integrated circuits (OEICs) undertaken mainly in university laboratories. OEIC transmitters and receivers for communications and semiconductor laser logic devices for optical switching and computing are briefly described.Optical and Quantum Electronics 04/1995; 27(5):305-317. · 0.82 Impact Factor
Article: A critical examination of room temperature ferromagnetism in transition metal-doped oxide semiconductors[show abstract] [hide abstract]
ABSTRACT: The current situation with the transition metal-doped oxide semiconductors, TiO2 and ZnO, regarding room temperature ferromagnetism is critically examined. It is provisionally concluded that the apparent ferromagnetism found in some samples stems from secondary phases. There is an indication that the room temperature ferromagnetism may be achieved by adding additional Cu to Fe-doped ZnO.Journal of Magnetism and Magnetic Materials.
