在1 T- TaS2和1 T- TaS1. 6Se 0. 4的滞后温度范围内,电脉冲诱导了多阻态

摘要:

研究了1 T-TaS_2和1 T-TaS_(1. 6)Se_(0.4)晶体在电脉冲作用下的电滞温区公度电荷密度波(CCDW)相响应。我们观察到,在一定温度下,电脉冲激发电阻的突变多个阶跃,形成多个亚稳态。我们认为系统的响应对应于CCDW畴结构的重排,而电脉冲激发的多电阻态或非易失性电阻特性对固态器件的探索具有深远的意义。

英文摘要:

The electric pulse-induced responses of 1T-TaS2 and 1T-TaS1.6Se0.4 crystals in the commensurate charge-density-wave (CCDW) phase in the hysteresis temperature range have been investigated. We observed that abrupt multiple steps of the resistance are excited by electric pulses at a fixed temperature forming multi metastable like states. We propose that the response of the system corresponds to the rearrangements of the textures of CCDW domains and the multi-resistance states or the nonvolatile resistance properties excited simply by electric pulses have profound significance for the exploration of solid-state devices.
