Opis:: Wire patterns (80-1000 nm) of molecular beam epitaxy grown Cd$\text{}_{0.2}$Zn$\text{}_{0.8}$Se/ZnSe quantum well were fabricated by a CH$\text{}_{4}$/H$\text{}_{2}$ reactive ion etching technique. Photoluminescence emission shows with decreasing lateral size a broadening of line shape and a spectral red shift. Calculations for the change of the band gap due to strain relaxation show that this shift of the photoluminescence emission for narrow Cd$\text{}_{0.2}$Zn$\text{}_{0.8}$Se/ZnSe structures (lattice mismatch of 1.34%) can be explained by a partial elastic strain relaxation of the biaxially compressively strained Cd$\text{}_{0.2}$Zn$\text{}_{0.8}$Se quantum well after the patterning process.

Opis:: Coexisting low-energy scales are observed in f-electron materials. The information about some of low-energy scales is imprinted in the electron self-energy, which can be measured by angle-resolved photoemission (ARPES). Such measurements in d-electron materials over the last decade were based on high energy- and momentum- resolution ARPES techniques used to extract the self-energy information from measured spectra. Simultaneously, many-body theoretical approaches have been developed to find a link between the self-energy and many-body interactions. Here we show the transcription of such methods from d-electrons to f-electrons by presenting the first example of low energy scales in the f-electron material $USb_2$, measured with synchrotron-based ARPES. The proposed approach will help in answering the fundamental questions about the complex nature of the heavy fermion state.
