标题： Electrolyte gate-controlled Kondo effect in SrTiO3

摘要： 我们报告了通过离子凝胶电解质门控的SrTiO3的低温、高场磁输运测量。对于更高的栅极电压，出现饱和电阻上升和负磁阻，这些现象表明Kondo效应的出现。这一观察结果得益于离子凝胶施加电场的宽广可调性，促进了对SrTiO3中由电场效应诱导的二维电子系统作为磁性Ti3+离子（即局域且未配对的电子）和部分填充Ti 3d导带的离域电子混合物的解释。 显示英文摘要

摘要： We report low-temperature, high-field magnetotransport measurements of SrTiO3 gated by an ionic gel electrolyte. A saturating resistance upturn and negative magnetoresistance that signal the emergence of the Kondo effect appear for higher applied gate voltages. This observation, enabled by the wide tunability of the ionic gel-applied electric field, promotes the interpretation of the electric field-effect induced 2D electron system in SrTiO3 as an admixture of magnetic Ti3+ ions, i.e. localized and unpaired electrons, and delocalized electrons that partially fill the Ti 3d conduction band.
