This work shows that despite a lattice mismatch of almost 20%, CdMnTe/CdTe/CdMnTe heterostructures grown directly on si(111) have surprisingly good optical emission properties. The investigated structures were grown by molecular beam epitaxy and characterized by scanning transmission electron microscopy, macro-and micro-photoluminescence. Low temperature macro-photoluminescence experiments indicate three emission bands which depend on the CdTe layer thickness and have different confinement characteristics. Temperature measurements reveal that the lower energy emission band (at 1.48 eV)is associated to defects and bound exciton states, while the main emission at 1.61 eV has a weak 2D character and the higher energy one at 1.71 eV has a well-defined (zero-dimensional, 0D) 0D nature. Micro-photoluminescence measurements show the existence of sharp and strongly circularly polarized (up to 40%) emission lines which can be related to the presence of Mn in the heterostructure. This result opens the possibility of producing photon sources with the typical spin control of the diluted magnetic semiconductors using the low-cost silicon technology.

This study unveils a novel and potentially economical particulate discrete element modeling (DEM) technique for large-scale simulation of in-situ direct shear tests (DsT) and plate load tests， aimed at accurately determining the shear strength and bearing capacity of granular soil foundations， and exploring the key factors influencing these properties. To overcome the limitations associated with the oversimplification of particle shapes， this work introduces an innovative contact model based on the Hertz contact mechanism that incorporates rolling resistance， enhancing the model’s ability to simulate realistic particle interactions. Guided by prandtl’s foundation bearing-capacity theory， the dimensions of the foundation model for the DsT and plate load tests were meticulously calculated to reflect realistic conditions. DEM simulations showed the peak friction angle from in-situ DsT to be consistently lower than laboratory DsT， due to a smaller dilatation angle， while proposed loading methods for plate load tests established linear relationships between the foundation’s ultimate bearing capacity and its dimensions， also defining the capacity envelope. Crucially， this study highlights a crucial finding: in-situ direct shear tests (DsT) conducted under high normal stress may lead to foundation failure， indicating that excessive normal stress should be avoided to ensure the accuracy of in-situ shear test data and its subsequent applicability in engineering design.
