Disclosed are a spin transistor and a method of operating the spin transistor. The disclosed spin transistor includes a channel formed of a magnetic material selectively passing a spin-polarized electron having a specific direction, a source formed of a magnetic material, a drain, and a gate electrode. When a predetermined voltage is applied to the gate electrode, the channel selectively passes a spin-polarized electron having a specific direction and thus, the spin transistor is selectively turned on.

Provided are a memory device, a method of manufacturing the same, and a method of operating the same. The memory device may include a channel region having an upper end where both sides of the upper end are curved, the curved portions of both sides allowing charges to be injected thereinto in a program or erase voltage such that the curved portions into which the charges are injected are separate from a portion which determines a threshold voltage, and a gate structure on the channel region.

摘要:
A spiro-based compound containing cyclopentaphenanthrene and fluorene, which is used for an organoelectroluminescent device and an organoelectroluminescent device having the spiro-based compound. The spiro-based compound containing cyclopentaphenanthrene and fluorene can be easily manufactured to have high solubility, high color purity, and good thermal stability. The spiro-based compound containing cyclopentaphenanthrene and fluorene is suitable as a substance for an organic film, in particular, an emission layer of an organoelectroluminescent device. Further, the spiro-based compound containing cyclopentaphenanthrene and fluorene can be used as an organic dye, or an electron material such as a non-linear optical material.
