Under which conditions does preferential growth occur in PLD grown films?

In the literature one can find examples for preferential and non preferential growth using PLD. My question would be does this depend on the material (internal) or on external parameters such as...

Why cant the Ti(+IV) in TiO2 be reversible reduced to oxidation state lower than Ti(+III) during reaction with lithium?

Ti in TiO2 undergoes only an intercalation reaction with max reversible reduction to Ti(+III) while Ti in TiSnSb undergoes a reversible conversion reaction (from Ti+IV reduced to metallic Ti). Why...

What is the approximate error of a nitrogen physisorption, BET based specific surface area analysis for nano-structured materials with 50-150m2/g?

For the measurement, we weighed sufficient material to reach specific surface area of min 10m2, furthermore we used a high precision scale (d=0.1mg)
