A spin-polarized donor, BTBN, which is a dibromotetrathiafulvalene derivative containing a nitronyl nitroxide group in a cross-conjugated manner, was prepared. Upon hole injection from an electrode, the neutral microcrystals of BTBN exhibited nonlinear I-V characteristics that were interpreted in terms of the space-charge-limited conduction (SCLC)(More)
The spiral vector theory is proposed. In AC circuit theories it unifies steady-state AC theory and transient-state theory by providing common variable expressions. In analyses of three phase machines the spiral vector method makes it possible to write performance equations in terms of variables of one phase (the phase segregation method). Based on the(More)
