Ulwazi lokuqhubekeka komphezulu wokuqengqeleka kweumbhobho wensimbi engenasici:
1. Emva kokuqengqeleka okushushu, ukuqholwa, ukucholwa, kunye nokuhla, umphezulu wepleyiti yentsimbi ephathwayo ngumhlaba obuthuntu kwaye urhabaxa;
2. Yinkqubo engcono kunomphezulu jikelele, kwaye iphinde ibe yindawo epholileyo. Emva kokuqengqeleka okubandayo, i-anneal, ukuhla, kwaye ekugqibeleni ukukhanya kuqengqeleka ngomqulu orhabaxa;
3. Le yeyona nto isetyenziswa kakhulu kwizicelo zokwakha. Ngaphandle kokuqengqeleka kokugqibela okupholileyo okupholileyo kunye nerola yokupholisha emva kokuba i-annealing kunye nokuhla, ezinye iinkqubo ziyafana ne-2D, umphezulu uyabengezela kancinci, kwaye unokugudiswa;
4. Ukucoca okuqaqambileyo:
(a) Lo ngumgangatho okhanyayo, osongwa ngeeroli zokumenyezeliswa ze ekugqibeleni zifakwe kwiatmosfera elawulwayo;
(b) I-annealing eqaqambileyo isawugcina umphezulu okhanyayo kwaye awuvelisi isikali se-oxide.
