Modeling of Charge Transport in Ion Bipolar Junction Transistors
Langmuir, 2014 Spatiotemporal control of the complex chemical microenvironment is of great importance to many fields within life science. One way to facilitate such control is to construct delivery circuits, comprising arrays of dispensing outlets, for ions and charged biomolecules based on ionic transistors.
