您要查找的是不是：
- Conventional resonant tunnel diodes allow currents to flow at a specific voltage, one at which the electrons have an energy that is resonant with the tunneling barrier. 传统共振穿隧二极体在特定电位下可让电流通过，此时电子的能量共振于（即等于）穿隧位障。
- The results show that the change of surface Cr_2O_3 thickness induces to the difference in tunneling barrier, which alters magnetotransport properties of CrO_2. 实验结果表明CrO_2颗粒表面Cr_2O_3层厚度的改变导致颗粒间隧穿势垒的变化，从而使CrO_2颗粒间的磁输运性质发生了改变。
