Special Issue Information

Dear Colleagues,

There has been an alarming increase in atmospheric CO2 content recently, mainly due to the use of fossil fuels for energy generation. While a significant portion of this CO2 is associated with the transport sector, the building sector also accounts for a large portion of energy use. For example, buidlings are consuming 40% of the total world’s energy and are contributing to 30% CO2 emission. This is expected to further increase in the coming years due to further growth in population and the building sector. Therefore, there is an urgent requirement to adopt designs which improve energy efficiency of buildings. This can be done by using renewable energy sources for power generation for the building sector, replacing the conventional building materials with photovoltaic materials or coating the windows to improve its heat transmitance and insulation efficiency as well as integrating emerging energy harvesting technologies such as triboelectricity. In this Special Issue, we are inviting papers related to coatings for energy efficient buildings.

In particular, the topics of interest include but are not limited to:

  • Building integrated photovoltaics (BIPVs);
  • Thermochromic and electrochromic coating for smart windows;
  • Smart lighting for buildings;
  • Coatings for energy harvesting (triboelectricity, thermoelectricity, piezoelectricity).

To realize practical applications of nanowire-based devices, it is critical, yet challenging, to control crystal structure growth of III-V semiconductor nanowires. Here, we demonstrate that controlled wurtzite and zincblende phases of InAs nanowires can be fabricated using bismuth (Bi) as a surfactant. For this purpose, catalyst free selective area epitaxial growth of InAs nanowires was performed using molecular beam epitaxy (MBE). During the growth, Bi was used which may act as a wetting agent influencing the surface energy at growth plane ends, promoting wurtzite crystal phase growth. For a demonstration, wurtzite and zincblende InAs nanowires were obtained with and without using Bi-flux. Photoluminescence spectroscopy (PL) analysis of the nanowires indicates a strong correlation between wurtzite phase and the Bi-flux. It is observed that the bandgap energy of wurtzite and zincblende nanowires are ∼0.50 eV and ∼0.42 eV, respectively, and agree well with theoretical estimated bandgap of corresponding InAs crystal phases. A blue shift in PL emission peak energy was found with decreasing nanowire diameter. The controlled wurtzite and zincblende crystal phase and its associated heterostructure growth of InAs nanowires on Si may open up new opportunities in bandgap engineering and related device applications integrated on Si. Furthermore, this work also illustrates that Bi as a surfactant could play a dynamic role in the growth mechanism of III-V compound semiconductors. Full article
