“…The LPEE growth technique was actually developed during the use of electric current for dopant modulation in liquid phase epitaxy (LPE) [3], and then became a solution growth technique for the growth of semiconductor crystals (see for instance Refs. [4][5][6][7][8][9][10][11][12][13]). In LPEE, the applied electric current is the only driving force for mass transport.…”
