Title:
STRONGLY CORRELATED OXIDE FIELD EFFECT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/172898
Kind Code:
A1
Abstract:
[Problem] To provide a strongly correlated oxide field effect element that exhibits a switching function with phase transition by electrical means. [Means for solution] Disclosed is a strongly correlated oxide field effect element (100) comprising: a channel layer (2) made of a strongly correlated oxide thin film; a gate electrode (41); a gate insulating layer (31); and a source electrode (42) and a drain electrode (43). The channel layer (2) includes an insulation metal transition layer (22) of strongly correlated oxide and a metal state layer (21) of strongly correlated oxide that are arranged one on top of the other. The thickness (t) of the channel layer (2), the thickness (t1) of the insulation metal transition layer (22), and the thickness (t2) of the metal state layer (21) satisfy the relationship t=t1+t2≥t1c>t2c where t1
