Stability and kinetics of step motion on crystal surfaces.

The kinetics of monoatomic steps in diffusion-controlled crystal growth and evaporation processes are investigated analytically using a Green’s function approach. Integro-differential equations of motion for the steps are derived; and a systematic linear stability analysis is carried out treating simultaneously perturbations both along and perpendicular to the steps. Morphological fluctuations ...

Step-related growth phenomena on exact and misoriented (OOl> surfaces of CVD-grown single-crystal diamonds

This study gives an overview of growth phenomena observed on {OOl} homoepitaxial diamond films grown by hot-filamentassisted CVD and acetylene-oxygen flame deposition. The main emphasis lies on the nucleation and propagation of steps, which form a key to understanding the growth on the (2 x I) reconstructed (001) faces.

Physicochemical evaluation, study of stability and drug release kinetics from

Introduction: Acne is a disorder of the pilosebaceous unit of the skin and can present as non inflammatory and or inflammatory lesions. Tretinoin has been used therapeutically for over three decades. It is best known for its comedolytic effects on acne. It also inhibits comedone rupture, thus decreasing inflammatory events. Tretinoin is available in 0.01% to 0.1% as cream, gel or lotion. The ...
