DILUTE MAGNETIC SEMICONDUTOR AND FABRICATION MEHTOD OF THE SAME

摘要

PURPOSE: A dilute magnetic semiconductor is provided to increase the non-surface area by making TiO2 power in which the transition metal is doped through the hydrothermal synthesis method with the titanate nanotube. CONSTITUTION: A dilute magnetic semiconductor is the nanotube consisting of the hydrogen titanate in which the transition metal is doped. The transition metal is the selected one from the group consisting of Ni, and Co and Fe element. In the room temperature, the dilute magnetic semiconductor has the curie temperature in a temperature less than 400K and has ferromagnetism.
