Key Points

The aim is to critique the effectiveness of electron-interfered field-effect transistors compared to organic charge-modulated ones.
Critiqued electron-interfered field-effect transistors (EIFET)
Compared EIFET performance to organic charge-modulated field-effect transistors (OCMFET)
Analyzed gate current generation due to charge
Explained limitations of EIFETs in detecting chemical reactions.
Identified flaws in EIFETs related to gate currents
Demonstrated that charge creates currents instead of effective shifts
Argued that OCMFETs serve as a valid standard for comparison.

Abstract

This comment critiques electron-interfered field-effect transistors (EIFET), using organic charge-modulated (OCMFET) ones as the valid standard. EIFETs are flawed; charge creates gate currents, not shifts.
