Voltage-Pulse Induced Resistance Switching Characteristics in a Cr-Doped SrZrO3

Abstract

The time resolved bipolar resistance switching in a Pt/Cr-doped SrZrO3/SrRuO3 device has been investigated using pulse voltage The required switching time between high and low resistance states (HRS and LRS) is studied as a function of the pulse height and width The resistance switching is found to be less dependent on the pulse height in the short pulse region. For LRS -> HRS and HRS -> LRS switching minimum switching times of similar to 500 and similar to 100 ns are required respectively at a pulse height above the dc switching voltage The authors attribute the distinction in the switching time to different switching mechanisms (C) 2010 Japan Society of Applied Physics
