Next generation semiconductors
1. Resistivity-Switchable semiconductors
-
Molecular switches reversibly transform between their stable molecular structures, which are induced by the environmental stimuli, such as light, temperature, pH, electricity, and so on.
-
Photochromic molecules, one kind of molecular switches, response to light of specific wavelength with changes of structure, color, energy level, absorbance, dipole moment, and etc.
-
The photochromic molecules are utilized in organic electronics with reversible property change, especially switching of energy level between two stable states.
-
For instance, in the organic electronics, the photochromic molecules were introduced to organic field effect transistor to provide the third state in addition to on-off states, and to organic light-emitting diode for patterned luminescence.
2. Oxide semiconductors
-
The most successful fabrication strategy for high-performance soluble oxide TFTs is utilizing the energy band offset between two stacked layers.
-
We focus on the more effective methodology of forming charge accumulation layer of heterojunction oxide semiconductors.
