Interface density driven metal-to-insulator transition in nickelate based heterostructures

2025

Abstract

Heterostructures made of alternating metallic layers of Nd 0.7 La 0.3 NiO 3 and layers displaying a metal-to-insulator transition (such as SmNiO 3 ) have been grown varying the period of the superlattices on top of LaAlO 3 substrates. Exploiting the phase boundary cost found between metallic and insulating phases of nickelates, it is shown that a metallic layer can be turned into an insulating one by means of heterostructuring in an intermediate thickness regime in which the single layers retain their metallic behavior.

MOSFET

The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal-insulator-semiconductor field-effect transistor (MISFET) is a term almost synonymous with MOSFET.

Mott insulator

Mott insulators are a class of materials that are expected to conduct electricity according to conventional band theories, but turn out to be insulators (particularly at low temperatures). These insulators fail to be correctly described by band theories of solids due to their strong electron–electron interactions, which are not considered in conventional band theory. A Mott transition is a transition from a metal to an insulator, driven by the strong interactions between electrons.

Thin film

A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering.
