Proximity-induced OP on the surface of Bi2Te3. We consider only the chiral p x  + ip y part of the total p + s OP. Close to the interface I the chiral term is modified: the p x (dashed line) and p y (straight line) components exhibit different magnitude. In case of high transparency interface (a), the two components are both suppressed in equal manner and the resulting interface OP still preserve the p x  + ip y wave character. For a low transparency interface (b), the p x component is highly suppressed while the p y slightly enhanced. The resulting OP has a predominantly p y character. c shows the amplitude of the resulting interface OP by considering a mixture p y  + iαp x , with α = 0.1. This corresponds to the reduction of p x on distances of the order of the coherence length of S′28. The corresponding phase is shown in d
