固体聚电解质已用于晶体管器件中以实现具有高电容的选通。我们使用固体聚环氧乙烷/LiClO 4电解质,以取代水电解质作为表面导电金刚石场效应晶体管(FET)的栅极。所得到的晶体管显示出与水电解质门控金刚石FET的特性相当的特性。我们研究了金刚石/金刚石界面的阻抗谱和循环伏安法,显示界面和电容门控高达100 Hz的电化学稳定性。霍尔效应测量的聚电解质门控设备进行比较,那些与液体门。固体和透明的金刚石栅极为表面导电金刚石FET提供了进一步的应用。
Solid polyelectrolytes have been used in transistor devices to achieve gating with high capacitance. We use a solid polyethylene oxide/LiClO4 electrolyte to replace aqueous electrolytes as a gate for surface-conductive diamond field-effect transistors (FET). The resulting transistor shows characteristics comparable to those of aqueous electrolyte-gated diamond FETs. We investigate the polyelectrolyte/diamond interface with impedance spectroscopy and cyclic voltammetry, showing the electrochemical stability of the interface and capacitive gating up to 100 Hz. Hall effect measurements on the polyelectrolyte-gated devices are compared to those with liquid gates. The solid and transparent polyelectrolyte gates promise further applications for surface-conductive diamond FETs.
