摘要

合成了二维单晶Gd2O5，由于其具有较强的离子极化能力，具有宽的带隙和高的介电常数（κ）。这些特性使基于mos2的晶体管能够实现极低的亚阈值摆幅和高的开/关电流比，突出了Gd2O5在先进晶体管应用中的潜力。

Ionic polarization modulation for wide-bandgap high-κ 2D insulators

2D monocrystalline Gd2O5 is synthesized, which exhibits a wide bandgap with a high dielectric constant (κ), attributed to its strong ionic polarization capability. These properties enable MoS2-based transistors to achieve an exceptionally low subthreshold swing and a high on/off current ratio, highlighting the potential of Gd2O5 for advanced transistor applications.
