Abstract:
According to the embodiment of the present invention, an ion field effect transistor having a heterogeneous triangular nanochannel includes a substrate, a polymer layer formed on the substrate and having a first flow path and a second flow path separated from the first flow path, and a gate electrode formed on the substrate and the polymer layer and touching the first and the second flow path. A heterogeneous triangular nanochannel connecting the first and the second flow path is formed between the gate electrode and the polymer layer.
