Biosynaptic devices based on chicken egg albumen (CEA):graphene quantum dot (GQD) hybrid nanocomposites were fabricated to achieve stable synaptic behaviors. Current-voltage (I-V) curves for the biosynaptic devices under consecutive negative and positive voltage sweeps showed clockwise pinched hysteresis, which is a critical feature of a biological synapse. The effect of the GQD concentration in the CEA layer on the device performance was studied. The retention time of the biosynaptic devices was relatively constant, maintaining a value above 104 s under ambient conditions. The carrier transport mechanisms of the biosynaptic devices were described and analyzed on the basis of the slopes of the I-V curves and their fittings.

基于鸡蛋蛋白的生物突触装置:石墨烯量子点纳米复合材料。



制备了基于鸡蛋蛋白(CEA):石墨烯量子点(GQD)混合纳米复合材料的生物突触装置,以实现稳定的突触行为。生物突触装置在连续负电压和正电压扫描下的电流-电压 (IV) 曲线显示出顺时针收缩磁滞,这是生物突触的一个关键特征。研究了CEA层中GQD浓度对器件性能的影响。生物突触装置的保留时间相对恒定,在环境条件下保持在 104 秒以上。根据 IV 曲线的斜率及其拟合描述和分析了生物突触装置的载流子传输机制。
