AB  - In the present work, we demonstrate the potential of double gate junctionless 
      (JL) architecture for enhanced sensitivity for detecting biomolecules in cavity 
      modulated field effect transistors (FETs). The higher values of body factor, 
      achieved in asymmetric gate operation under impact ionization is utilized for 
      enhanced sensing margin which is nearly five times higher than compared to 
      symmetrical mode operation. The intrinsic detection sensitivity is evaluated in 
      terms of threshold voltage change, and the ratio of drain current in the presence 
      and absence of biomolecules in JL nanotransistors. It is shown that asymmetric 
      mode JL transistor achieves a higher degree of detection sensitivity even for a 
      partially filled cavity. The work demonstrates the potential of JL channel 
      architecture for cavity based dielectric modulated FET biosensors.
