“…In particular, transport under microwave (MW) radiation field in high mobility 2DEGs revealed many intriguing and unexpected phenomena, of which MW-radiation induced magnetoresistance oscillations (MIRO) [3][4][5][6] and associated zeroresistance states (ZRS) [7,8] are probably the most striking manifestation. Therefore, nonequilibrium transport phenomena such as MIRO, ZRS, HIRO (Hall field-induced resistance oscillations) [9] and ZdRS (Zero-differential resistance states) [10], to mention but a few, in high-purity 2DEGs subjected simultaneously to MW radi-E-mail addresses: wywang2014@sina.cn (W.Y.…”
