Scaling law and dynamical exponent in the Volmer-Weber growth mode: silver on GaAs(001)2 x 4

, 2000
The growth of Ag deposited onto the GaAs(001)2 x 4 has been investigated by means of scanning tunnelling microscopy. Silver forms islands (Volmer-Weber growth) whose average dimension increases according to Theta(1/z) (with z = 4.2).

Advanced avrami formula and its application to describing the isothermal crystallisation of polymers

The classic Avrami formula has widely been used to describe and characterize the crystallisation process of polymers. We showed that the Avrami formula is not correct for the random nucleation.
