Typical chemical sensing materials include metal oxide semiconductors, conducting polymers, and emerging materials, such as graphene and carbon nanotubes, as well as composite materials.
In recent decades, most TE research has focused on inorganic materials such as semiconductors or conducting oxides [1 3].
Substances with larger energy gaps are generally insulators, materials with smaller energy gaps are semiconductors, and conducting materials have very small or no energy gaps.
We synthesized compound 1 as a fundamental electron-accepting building block for the design of n-type semiconductors and conducting polymers.
MWCNTs have two crucial roles in catalytic enhancement on AP thermal decomposition: firstly, being to act as a supporter which can effectively disperse copper and Bi2O3 particles; secondly, being to act as a bridge, excited electrons from semiconductor can conduct and store on the surfaces of MWCNTs, which is beneficial for AP thermal decomposition.
The p-n junction in a semiconductor diode conducts current with one polarity of applied voltage but not with the other polarity.
In addition, compared with traditional metal or semiconductor materials, conducting polymers are more biocompatible.
With progressive downsizing of semiconductor devices, conducting polymers are a promising candidate for Ohmic contacts because of their variable size and work function.
Herein, besides carbon series semiconductor materials, conducting polymer is often used as functional element of devices due to their good electrical conductivity, physical robustness, and large surface area [3, 16, 17].
Thin-layer semiconductors, materials that conduct electricity poorly in the dark but allow electrons to flow freely when the sun shines, lie at the heart of this technology.
