    • The Effect of a Nucleation Layer on Morphology and Grain Size in MOCVD-Grown β-Ga2O3 Thin Films on C-Plane Sapphire 

      Dimitrocenko, Lauris; Strikis, Gundars; Polyakov, Boris; Bikse, Liga; Oras, Sven; Butanovs, Edgars (MDPI, 2022)
      β-Ga2O3 thin films grown on widely available c-plane sapphire substrates typically exhibit structural defects due to significant lattice and thermal expansion mismatch, which hinder the use of such films in electronic ...

    • Energy level determination in bulk heterojunction systems using photoemission yield spectroscopy: case of P3HT:PCBM 

      Grzibovskis, Raitis; Vembris, Aivars (Springer New York LLC, 2018)
      Ultraviolet photoelectron spectroscopy (UPS) is commonly used method for energy level determination using planar heterojunction samples in either metal/organic or organic/organic systems. Only some attempts have been made ...

    • ITO Thin Films for Low-Resistance Gas Sensors 

      Almaev, Aleksei V.; Kopyev, Viktor V.; Novikov, Vadim A.; Chikiryaka, Andrei V.; Yakovlev, Nikita N.; Usseinov, Abay B.; Karipbayev, Zhakyp T.; Akilbekov, Abdirash T.; Koishybayeva, Zhanymgul K.; Popov, Anatoli I. (MDPI, 2023)
      Indium tin oxide thin films were deposited by magnetron sputtering on ceramic aluminum nitride substrates and were annealed at temperatures of 500 °C and 600 °C. The structural, optical, electrically conductive and ...

    • Sb2S3 solar cells with a cost-effective and dopant-free fluorene-based enamine as a hole transport material 

      Juneja, Nimish; Mandati, Sreekanth; Katerski, Atanas; Spalatu, Nicolae; Daskeviciute-Geguziene, Sarune; Vembris, Aivars; Karazhanov, Smagul; Getautis, Vytautas; Krunks, Malle; Oja Acik, Ilona (Royal Society of Chemistry, 2022)
      Antimony sulphide (Sb2S3) is a promising candidate for semi-transparent and tandem solar cells owing to its suitable optoelectronic properties. However, the applications of Sb2S3 solar cells are rather limited by their low ...

    • Sb2S3 Thin-Film Solar Cells Fabricated from an Antimony Ethyl Xanthate Based Precursor in Air 

      Eensalu, Jako S.; Mandati, Sreekanth; Don, Christopher H.; Finch, Harry; Dhanak, Vinod R.; Major, Jonathan D.; Grzibovskis, Raitis; Tamm, Aile; Ritslaid, Peeter; Josepson, Raavo; Käämbre, Tanel; Vembris, Aivars (American Chemical Society, 2023)
      The rapidly expanding demand for photovoltaics (PVs) requires stable, quick, and easy to manufacture solar cells based on socioeconomically and ecologically viable earth-abundant resources. Sb2S3 has been a potential ...

    • WO3 as Additive for Efficient Photocatalyst Binary System TiO2/WO3 

      Knoks, Ainars; Kleperis, Janis; Bajars, Gunars; Grinberga, Liga; Bogdanova, Olga (Walter de Gruyter, 2021)
      Two different methods of synthesis of TiO2/WO3 heterostructures were carried out with the aim to increase photocatalytic activity. In this study, anodic TiO2 nanotube films were synthesized by electrochemical anodization ...
