“…Note that in our labs, we can also monitor thin-film growth in real time with MOVPE using a method other than RHEED. These advantages of our MBE system have enabled us to discover novel superconductors [12,13] and a magnetic material [14], while some important growth parameters such as the flux ratio of cations, substrate materials, substrate temperature, and oxidation strength are systematically varied.…”

“…Precise control of doping and oxidation are some of the strong reasons that MBE is used to grow superconducting films and heterostructures. Extensive studies have been carried out on MBE-grown cuprates, such as La x Sr 1−x CuO 4 (LSCO), Bi 2 Sr 2 CuO 6+x (BSSCO), YBa 2 Cu 3 O 7−x (YBCO) and variants [89,90], often involving custom-designed MBE systems that allows finetuning of various subtle growth parameters [91]. There are two main challenges in the growth on superconducting cuprates: oxidation and stoichiometry control.…”

Molecular beam epitaxy (MBE), a workhorse of the semiconductor industry, has progressed rapidly in the last few decades in the development of novel materials. Recent developments in condensed matter and materials physics have seen the rise of many novel quantum materials that require ultra-clean and high-quality samples for fundamental studies and applications. Novel oxide-based quantum materials synthesized using MBE have advanced the development of the field and materials. In this review, we discuss the recent progress in new MBE techniques that have enabled synthesis of complex oxides that exhibit "quantum" phenomena, including superconductivity and topological electronic states. We show how these techniques have produced breakthroughs in the synthesis of 4d and 5d oxide films and heterostructures that are of particular interest as quantum materials. These new techniques in MBE offer a bright future for the synthesis of ultra-high quality oxide quantum materials.

“…One possible way to achieve this is by generating strain in thin films. This strain can be induced by the mismatch with the single crystal substrate (epitaxial), or by the presence of grain boundaries, stacking faults, intergrowth, defects (residual), among others [15][16][17][18][19][20][21][22][23][24][25]. More recently, YBa 2 Cu 3 O 7 (YBCO) has been deposited on piezoelectric substrates, managing to control the range and value of the strain by applying an electric field after the sample has been grown, obtaining reversible effects on the critical temperature and a linear dependence with the in-plane strain [26,27].…”

In this work, the effect of strain on the vibrational and electronic properties of the YBa2Cu3O7(YBCO) compound was studied through \textit{ab initio} calculations. For this, two structural models were used: a bulk model and a surface model (a monolayer with CuO2 and BaO as the terminating layers). The phonon spectra was calculated for both structures under different levels of c axis strain. The most appreciable change occurs in the vibrational properties, and in the surface case. From the simulation of the Raman spectra, we were able to quantify the Raman shift ratio as a function of the applied strain, and analyzed its behavior in terms of the overlap population of the different bonds and the reduced mass of selected phonons. The effect of the level of deformation on the band structure and the electronic density of states is small for both structures, although more noticeable in the case of the surface model. In both cases, tendencies are observed when the fine features of the band structure are analyzed by means of the tight binding model. Due to the lower symmetry, the surface model also shows modifications of the bands related to the CuO2 planes.
