Note the different magnitudes of currents crossing the junction. In equilibrium (i.e. in the dark) both the diffusion and drift current are small. Under short circuit conditions, the minority carrier concentration on either side of the junction is increased and the drift current, which depends on the number of minority carriers, is increased.

Tunable Circular Photogalvanic and Photovoltaic Effect in 2D

Chirality arises from the asymmetry of materials, where two counterparts are the mirror image of each other. The interaction between circular-polarized light and quantum materials is enhanced in chiral space groups due to the structural chirality. Tellurium (Te) possesses the simplest chiral crystal structure, with Te atoms covalently bonded into a spiral atomic chain (left
