Recently deoxyribonucleic acid (DNA) has been studied as one of the interesting candidates for future electronic materials due to its natural plentitude, biodegradability, low cost, and low toxicity. Since DNA has poor solubility in typical organic solvent, it can hardly be deposited on substrate for channel or gate dielectric layer, except few cases where DNA polymer dielectric showed unstable electrical properties in its thin-film transistor applications mainly due to ionic impurities. In contrast, DNA-base small molecules such as guanine, cytosine, adenine, and thymine, which are constructing components of DNA polymer, can be readily deposited by thermal evaporating system to be patterned by conventional method (i.e. shadow mask). Here, we report on charge-injection type memory property and inverter logic circuit using nucleobase (DNA-base) small molecules as a part of dielectric layer. |
