TI  - DNA-base guanine as hydrogen getter and charge-trapping layer embedded in oxide 
      dielectrics for inorganic and organic field-effect transistors.

AB  - DNA-base small molecules of guanine, cytosine, adenine, and thymine construct the 
      DNA double helix structure with hydrogen bonding, and they possess such a variety 
      of intrinsic benefits as natural plentitude, biodegradability, biofunctionality, 
      low cost, and low toxicity. On the basis of these advantages, here, we report on 
      unprecedented useful applications of guanine layer as hydrogen getter and charge 
      trapping layer when it is embedded into a dielectric oxide of n-channel inorganic 
      InGaZnO and p-channel organic heptazole field effect transistors (FETs). The 
      embedded guanine layer much improved the gate stability of inorganic FETs 
      gettering many hydrogen atoms in the gate dielectric layer of FET, and it also 
      played as charge trapping layer to which the voltage pulse-driven charges might 
      be injected from channel, resulting in a threshold voltage (Vth) shift of FETs. 
      Such shift state is very ambient-stable and almost irrevocable even under a high 
      electric-field at room temperature. So, Boolean logics are nicely demonstrated by 
      using our FETs with the guanine-embedded dielectric. The original Vth is 
      recovered only under high energy blue photons by opposite voltage pulse 
      (charge-ejection), which indicates that our device is also applicable to 
      nonvolatile photo memory.
