介观晶体BSCCO的太赫兹辐射
Terahertz wave emission from mesoscopic crystals of BSCCO
摘要：
从理论上研究了外加磁场作用下BSCCO的太赫兹辐射机制。总功率与层数和频率的平方成比例。在小尺寸限制下，角分布与偶极发射中的角分布相似。与以前的模拟结果相比，目前的太赫兹功率输出的理论结果与实验结果在同一数量级。还观察到一系列与尺寸相关的固有频率。当外电流引起的外频率与本征频率共振时，观察到明显的太赫兹辐射。
英文摘要：
We study the Terahertz (THz) emission mechanism in BSCCO with an external magnetic field theoretically. The total power is proportional to the square of the number of layers and the frequency. Under the small size limitation, the angular distribution is similar to that in the dipole emission. The present theoretical results for THz power output are in the same order of magnitude as the experimental ones, in contrast with previous simulations. A series of size-dependent intrinsic frequencies are also observed. When the external frequency induced by the external current resonates with intrinsic ones, the distinct THz emission is observed.
