Clarification and exploration of novel transport phenomena caused by electron-electron interactions and spin degrees of freedom in molecular crystals

我们测量了有机晶体绝缘体的低温非线性电流-电压特性、介电性质和由电子-电子库仑相互作用引起的磁导，并阐明了它们的输运机制。莫特和电荷序绝缘体在零磁场下表现出相同的输运性质，但它们的磁导率不同，这是由于不同的自旋状态的载流子，有助于导电性。我们还进行了测量，使用微加工电极和微波辐射下。

We have measured the low-temperature nonlinear current-voltage characteristics, dielectric properties, and magnetoconductance of organic crystalline insulators caused by electron-electron Coulomb interaction and clarified their transport mechanism. The Mott and charge-order insulators exhibit the same transport properties at zero magnetic field, but their magnetoconductances differ due to different spin states of the carriers that contribute to the conductivity. We have also performed measurements using micro-fabricated electrodes and under microwave irradiation.
