“…Many nanoporous materials have been assembled by this method, such as GaAs [ 13 , 30 , 31 ], Si [ 17 , 18 , 26 , 32 ], GaP [ 23 , 28 , [33] , [34] , [35] , [36] ] and GaN [ 13 , 37 , 38 ]. Electrochemical etching and applications of InP nanopores have also attracted a lot of attention [ 27 , [39] , [40] , [41] , [42] , [43] , [44] , [45] ]. However, there are few specific reviews on electrochemical etching experimental devices and methods for InP.…”
