Exploring materials with multiple properties who can endow a simple device with integrated functionalities has attracted enormous attention in the microelectronic field. One reason is the imperious demand for processors with continuously higher performance and totally new architecture. Combining ferroelectric with semiconducting properties is a promising solution. Here, we show that logic, in-memory computing, and optoelectrical logic and non-volatile computing functionalities can be integrated into a single transistor with ferroelectric semiconducting α-In₂Se₃ as the channel. Two-input AND, OR, and non-volatile NOR and NAND logic operations with current on/off ratios reaching up to five orders, good endurance (1000 operation cycles), and fast operating speed (10 μs) are realized. In addition, optoelectrical OR logic and non-volatile implication (IMP) operations, as well as ternary-input optoelectrical logic and in-memory computing functions are achieved by introducing light as an additional input signal. Our work highlights the potential of integrating complex logic functions and new-type computing into a simple device based on emerging ferroelectric semiconductors.

探索具有多种特性的材料，可以赋予一个简单的设备以集成功能，在微电子领域引起了极大的关注。原因之一是对性能不断提高和全新架构的处理器的迫切需求。将铁电体与半导体特性相结合是一种很有前途的解决方案。在这里，我们展示了逻辑、内存计算、光电逻辑和非易失性计算功能可以集成到具有铁电半导体 α-In ₂ Se _{3的单个晶体管中}作为频道。实现了双输入AND、OR、非易失性NOR、NAND逻辑运算，电流开/关比可达5个数量级，耐久性好（1000次运算周期），运算速度快（10μs）。此外，光电或逻辑和非易失蕴涵（IMP）运算，以及三元输入光电逻辑和内存计算功能都是通过引入光作为附加输入信号来实现的。我们的工作突出了将复杂逻辑功能和新型计算集成到基于新兴铁电半导体的简单设备中的潜力。
