论文摘要
开发的材料可以导致人工神经元（神经主）和突触（Memristors）的紧凑版本是新生的神经形态材料研究领域的主要吸引力。振荡电路很有趣，因为神经主医生模仿动作电位的发射。我们提出了由半导体TBMNO3的外延薄膜制成的室温自振荡设备。我们表明，这些电振荡引起了产生可听见声波的机械振荡，从而提供了与其他设备接口的额外自由度。控制振荡机制的内在性质会产生高度的控制和重复性。在外延钙钛矿氧化物中获得此类特性，为将自振荡性特性与其他压电，铁电或磁性钙钛矿氧化物的特性开辟了道路，以实现杂种神经化神经晶体管菌功能在紧凑型杂质中。
Developing materials that can lead to compact versions of artificial neurons (neuristors) and synapses (memristors) is the main aspiration of the nascent neuromorphic materials research field. Oscillating circuits are interesting as neuristors, emulating the firing of action potentials. We present room-temperature self-oscillating devices fabricated from epitaxial thin films of semiconducting TbMnO3. We show that these electrical oscillations induce concomitant mechanical oscillations that produce audible sound waves, offering an additional degree of freedom to interface with other devices. The intrinsic nature of the mechanism governing the oscillations gives rise to a high degree of control and repeatability. Obtaining such properties in an epitaxial perovskite oxide, opens the way towards combining self-oscillating properties with those of other piezoelectric, ferroelectric, or magnetic perovskite oxides to achieve hybrid neuristor-memristor functionality in compact heterostuctures.
