Summary:
Surfaces of SrTiO3 (STO) are widely known as a playground of basic physical researches of two-dimensional metallic systems. By electrostatic carrier-density modulation of the STO surface, a variety of interesting phenomena such as an insulator to 2D metal transition (IMT), superconductivity, and ferromagnetism are triggered. Here we demonstrate a unique challenge; neuromorphic electronic devices are implemented on the electrostatic control of the IMT at the STO surface.We prove that our STO device is indeed a promising candidate of an artificial neuron (leaky-integrate and fire: LIF) as well as an artificial synapse (spike-timing-dependent plasticity: STDP). This work will bridge the gap between the basic research of IMT and its viable applications.
