Quantum dots — a category of man-made molecules — are one of several promising materials niche sectors that have recently emerged from the burgeoning growth area of nanotechnology, falling into the category of nano crystals, which also includes quantum rods and nano wires.
These minuscule nanocrystal semiconductors are still flying pretty much under the radar of popular perception. However, because quantum dots can be used as an enabling material across many industries, and claimed to be both unparalleled in versatility and flexible in form, it is projected that they will soon revolutionize production of transistors, solar cells, LEDs, and diode lasers, which should raise their profile with the public. Quantum dots are also being researched as agents for medical imaging and as possible qubits (quantum bits – a unit of quantum information in quantum computing).
As a materials subset, quantum dots are characterized by material particles fabricated to the smallest of dimensions (2 nm -5 nam) –
small enough to display quantum mechanical properties from only a few atoms and upwards. They behave according to the rules of quantum physics, which describe the behavior of atoms and sub atomic particles, in contrast to classical physics that describes the behavior of bulk materials, or in other words, objects consisting of many atoms.Quantum Dots measure near one billionth of an inch and are a non-traditional type of semiconductor that can be used as an enabling material across many industries and claimed to be unparalleled in versatility and flexible in form.
Electrons in Quantum Dot (QD) nanoparticles are confined in all the three spatial dimensions, causing them to display unique optical, electrical, and mechanical characteristics, making them an attractive option for manufacturing next-generation devices in the lighting, display, solar energy, and healthcare categories.
As Quantum Dot possibilities become product realities they will increase the standard of living for people around the world, and not just in developed countries, as electricity becomes portable and plentiful while at the same time electronic products become ubiquitous and inexpensive.
The quantum dot era is thus forecast to create a new paradigm of science and business highlighted by:
- Synthesis and Mass-Production of Highly Functionalized Colloidal Tetrapod Quantum Dots
- Mass-Production of Printed Thin-Film PV Quantum Dot Solar Cells
- Mass-Production of Printed Electronics
The list of possible quantum dot applications is ever-expanding, with creative new applications waiting only for the economic availability of quantum dots, enabling realization of the potential to create a multitude of new jobs that will be made possible by quantum dot based industry. Quantum dot based applications are projected that will create or save energy, diagnose, treat and cure formidable diseases, and that are Green because quantum dot solar cell manufacture is the cleanest way to create energy. It is predicted that Quantum Dot possibilities will become product realities that will increase the standard of living globally as electricity becomes portable and plentiful, along with electronic products that will become even more ubiquitous and inexpensive.
About Tetrapod Quantum Dots
Tetrapod (4 arms) shaped QD outperform all other QD shapes due to their better abilities in charge transport and multiple exciton generation (MEG). Research done by Texas-based nano tech firm Quantum Materials Corporation (QMC), which manufactures quantum dots, shows that Tetrapod Quantum Dots exhibit a unique potential to better the performance of the ‘industry standard’ spherical quantum dots.”I believe that our inherent process improvements will result in higher uniformity and less defects in the near future, and will enable tailored solutions for many device applications,” says QMC Vice President for Research and Development David Doderer. “High material performance, combined with our ability to soon provide the industry with the commercial production they need, should well meet the increased demand for Tetrapod Quantum Dot products.”
