低维无机功能材料电学行为的调控主要依赖于本征异质原子掺杂,但是该方法在性质调控的同时,由于异质原子的嵌入常导致原有晶体结构对称性发生改变,产生变形扭曲甚至破坏.目前,基于清晰结构调控无机材料功能性依然是极具挑战性的难题.氢作为一种小半径轻原子,对低维无机功能材料的修饰或嵌入为调控无极功能材料物性带来了新思路,特别是通过氢的嵌入可以在结构不发生大变化的前提下调制材料载流子浓度并提升导电率,这已逐渐成为低维无机材料电学行为调控的重要途径.本文概述了近年来发展的系列氢化调控方法,以及通过对电子结构调制实现对电学行为的调控,并基于此广泛应用于能源领域、电子器件及催化等方面.
The regulation of electrical behavior of low-dimensional inorganic functional materials mainly depends on the doping of intrinsic heterogeneous atoms. However, due to the nature regulation of the method, the imbalance of the original crystalline structure often leads to the distortion of the original crystal structure, Damage.At present, it is still a challenging problem to regulate the functionality of inorganic materials based on the clear structure.Hydrogen, as a kind of small radius light atom, brings new effects to the modification or embedding of low-dimensional inorganic functional materials The idea, especially through hydrogen embedding, can modulate the carrier concentration and enhance the conductivity without major changes in the structure, which has gradually become an important way to control the electrical behavior of low-dimensional inorganic materials.In this paper, the recent developments Series of hydrogenation control methods, and through the electronic structure modulation to achieve the regulation of electrical behavior, and based on this widely used in the field of energy, electronic devices and catalytic aspects.
