Abstract: A method for non-destructively determining parameters of a doped semiconductor material involves applying an excitation to a surface of the semiconductor material to photogenerate minority carriers in a region of the semiconductor material, presenting an electric field across the region of the semiconductor material, measuring photoluminescence produced by recombination of the photogenerated minority carriers, and using the photoluminescence measurements to compute one or more parameters of the doped semiconductor material. Excitation may involve pulsed or CW lasers. Computed parameters may include one or more of: the minority carrier mobility of the semiconductor material; the saturation drift velocity of minority carriers in the semiconductor material; the diffusion constant of minority carriers in the semiconductor material; the recombination lifetime of minority carriers in the semiconductor material; and/or the effective temperature of the semiconductor material.

Abstract: Based on the positions of characters that are supplied from a character position management unit, a communication control unit monitors whether or not another character is within a prescribed sphere that takes the position of a particular character as its center. The communication control unit permits the communication of information between the information communication unit of the user terminal device that corresponds to the particular character and the information communication unit of another character when the other character is within the prescribed sphere that takes the particular character as center. The communication control unit further automatically puts into effect a speech conference function that is realized between the information communication unit of the user terminal device that corresponds to the particular character and the information communication unit of the other character.
