By virtue of the high carrier mobility, diverse electronic band structures, excellent
electrostatic tunability, easy integration, and strong light-harvesting capability, 2D layered …

Structural or crystal asymmetry is a necessary condition for the emergence of zero-bias
photocurrent in light detectors. Structural asymmetry has been typically achieved via p–n …

An exact solution for electromagnetic wave diffraction at the junction of two-dimensional
electron systems (2DES) is obtained and analyzed for electric field polarized along the …

Polarization feature is one of the important features of radar targets, which has been used in
many fields. In this paper, the grid models of some typical foreign moving targets are …

The recently observed helicity-sensitive response, occurring in graphene based field-effect
transistors (FETs) is interpreted as a result of the intrinsic phase asymmetry of these devices …

Two-dimensional materials offering ultrafast photoresponse suffer from low intrinsic
absorbance, especially in the mid-infrared wavelength range. Challenges in 2d material …

A necessary condition for photodetection is the presence of nonlinearities for radiation
rectification and their asymmetry to obtain an uncompensated overall photoresponse. We …
