摘要:

本文研究了在面内磁场B_ip存在下,朗道能级填充为9/2的二维电子系统(2DES)条形相射频电导谱中的各向异性钉扎模式共振。随着施加B_ip,观察到共振的偏振切换,与条纹的重新取向一致。的共振频率,2DES和无序之间的钉扎相互作用的措施,增加与B_ip。这种增加的幅度表明,无序相互作用在确定条纹取向中起着重要的作用。

英文摘要:

We study the anisotropic pinning-mode resonances in the rf conductivity spectra of the stripe phase of 2D electron systems (2DES) around Landau level filling 9/2, in the presence of an in-plane magnetic field, B_ip. The polarization along which the resonance is observed switches as B_ip is applied, consistent with the reorientation of the stripes. The resonance frequency, a measure of the pinning interaction between the 2DES and disorder, increases with B_ip. The magnitude of this increase indicates that disorder interaction is playing an important role in determining the stripe orientation.
