Microstructures of GaN buffer layers grown on Si (111) substrates using rapid thermal process low-pressure metalorganic chemical vapor deposition are investigat
We have experimentally studied the surface modifications of Y-Ba-Cu-O (YBCO) thin films using CF4plasma. The intensity of the plasma fluorination was controlled
Some interesting behaviour of accreting particles in the gap region between the horizon of the Kerr black hole and the inner edge of the surrounding disc is inv
We generalize the Frenkel-Kontorov model to the Frenkel-Kontorova-Devonshire model in which the interaction is the triple-well potential. By use of the effectiv
Pt/Au Schottky contacts were fabricated on modulation-doped Alo.22GaNo. 7s/GaN heterostructures. Some dif-ferent pre-deposition surface treatments were used to
We improve the brick-wall model to take only the contribution of a thin film near the event horizon into account. This improvement not only gives us a satisfact
