Impact of nanogap thickness on dielectric-modulated field-effect transistor biosensor performance for uncharged biomolecules detection

Uncharged biomolecules sensing performance of dielectric-modulated field-effect transistor (DMFET) biosensor at various nanogap thickness via semiconductor device simulation tool was assessed in this work. The device structures with 10 nm-, 15 nm-, and 20 nm-thick nanogap were constructed for this i...
