The polystyrene/application of the derivatives of porphyrin composite nano fiber in transistorized memory, being will be described multiple
Close the electronics trapping layer that transistorized memory is made in nanofiber.
The present invention uses reception device of two parallel metal bars with same negative high voltage as electrostatic spinning, is determined
To polystyrene/derivatives of porphyrin composite nano fiber, i.e., arrangement with certain orientation composite nano fiber.Relative to
Conventional receiver mode obtains nanofiber, and nanofiber of the invention is transferred to SiO2Method on/Si substrates is simpler fast
Victory, integrates easy to ensuing memory.In addition, the nanofiber of orientation with the nanofiber being distributed in a jumble compared with lower
Roughness, and arrangement and the channel vertical of nanofiber is not in the parallel situation for isolating raceway groove, in orientated nano fibers
The pentacene of surface growth is more smooth, and then transistor field-effect also can be better.On this basis, nanofiber does charge-trapping
Layer, has the specific surface area of higher, more highdensity storage site can be formed in identical raceway groove, so as to be stored beneficial to improving
Window, meanwhile, nanofiber surface can form the built in field of higher and be transmitted beneficial to the effective of carrier.
Beneficial effect：
1. polystyrene/derivatives of porphyrin composite nano fiber is thinner than spin coating as the electronics trapping layer of transistorized memory
Film has the specific surface area of higher, and the storage density of higher can be reached in same raceway groove, and then improves the memory window of memory
Mouthful；
2. under same grid voltage, polystyrene/derivatives of porphyrin composite nano fiber surface energy forms the built-in electricity of higher
, transmitted beneficial to carrier in the effective of each function interlayer of device；
3. the doping concentration of derivatives of porphyrin is the 1% of PS weight, gained transistorized memory can reach the storage of 33V
Window, and device has higher reliability.
