SNIP: A new semiconductor material

Ref-Nr: TA-B75074


Kurzfassung

  • Tin phosphor iodide (SnIP) is a new semiconductor material
  • Photoluminescence in the visible makes it interesting for solar cells and light emitting diodes
  • First inorganic double helix structure material


Hintergrund

The new substance tin phosphor iodide (SnIP) consists of the elements tin (Sn), iodine (I) and phosphorus (P). This new substance is expected to appear in at least two chapters of future standard teaching books. This is the first inorganic material with a double-helical structure as well as a new semiconductor material. This second aspect in particular opens many interesting technical possibilities.

Lösung

SnIP and its analagues represent a new, exotic material with an unusual combination of ­interesting features:

  • Semiconductor with a bandgap in the range of 1.8eV
  • Photoluminescence (λmax = 670 nm)
  • Nanowires with a diameters of ~ 5 nm and lengths over centimeters
  • Thermal stability up to 500 °C
  • Non-toxic


With these features and low-cost synthesis, outstanding application possibilities in the field of photovoltaics and in the LED sector can be expected. However, similar to graphene, it is to be expected that various other unconventional applications will be discovered. For example, it is conceivable to use the flexible nanowires for the contact-connection of semiconductor structures.
