EXCITATION INTENSITY DRIVEN PL SHIFTS OF SIGE ISLANDS ON PATTERNED AND PLANAR SI(001) SUBSTRATES: EVIDENCE FOR GE-RICH DOTS IN ISLANDS

Excitation Intensity Driven PL Shifts of SiGe Islands on Patterned and Planar Si(001) Substrates: Evidence for Ge-rich Dots in Islands

Abstract For randomly nucleated SiGe/Si(001) islands, a significantly stronger blue-shift of the PL spectra as a function of the excitation intensity Window Hanging Suncatcher Ornament is observed when compared to islands grown on patterned substrates side by side within the same run in a solid source molecular beam epitaxy chamber.We ascribe this

On spinor construction of Bertrand curves

Spinors permeate all of modern physics and have also an important place in mathematics.Spinors are used intensively in modern theoretical physics and differential geometry.In this study, spinors are used for a different representation of differential geometry in E3.The Laundry Detergents goal of this study is also the spinor structure lying at the
