Is the direct current (DC) heating method suitable for preparation of reconstructed Ge(hkl) substrates ?

For preparation of reconstructed Si(hkl) substrates, we generally employ direct current (DC) heating method in ultra-high vacuum (UHV) condition. In this case, initially we degas the Si(hkl)...
