With development of information age, multi-valued logic (MVL) technology utilizing negative differential transconductance (NDT) phenomenon has drawn attention as next-generation computing technology that can replace binary logic. However, because conventional NDT devices primarily use ternary logic, multiple-peak NDT device is required for higher-radix MVL that can process more datasets. Here, van der Waals double-peak anti-ambipolar transistor (AAT) as NDT device was developed by utilizing peak voltage (V_peak) modulation of NDT peak. For realization of quaternary logic, V_peak modulation technology was developed through charge transfer mechanism from channel, thereby shifting NDT peak and increasing peak-to-valley current ratio (PVCR). Furthermore, Double-peak AAT was implemented through parallel configuration of two AATs with different V_peak values. Finally, quaternary inverter with four widely stable logic states was implemented by utilizing the developed double-peak AAT with two distinct NDT peaks and high PVCR. This double-peak AAT is expected to contribute to the development of next-generation MVL technology capable of processing datasets.

随着信息时代的发展，利用负微分跨导（NDT）现象的多值逻辑（MVL）技术作为可以取代二进制逻辑的下一代计算技术而受到关注。然而，由于传统的NDT设备主要使用三元逻辑，因此需要多峰NDT设备来实现可以处理更多数据集的更高基数的MVL。_{这里，利用NDT峰值的峰值电压（ Vpeak} ）调制开发了范德华双峰抗双极晶体管（AAT）作为NDT器件。为了实现四进制逻辑，通过通道电荷转移机制开发了V_峰值调制技术，从而移动NDT峰值并提高峰谷电流比（PVCR）。此外，双峰AAT是通过两个具有不同V峰值的AAT并联配置来实现_的。最后，利用所开发的具有两个不同NDT峰值和高PVCR的双峰AAT实现了具有四种广泛稳定逻辑状态的四元逆变器。这种双峰 AAT 预计将有助于开发能够处理数据集的下一代 MVL 技术。
