Physicists created an exotic electronic liquid

By influencing an ultra-thin layered semiconductor with powerful laser pulses, researchers were first possible to create a liquid consisting of conventional atoms of a substance, but only from individual electrons and holes at room temperature.

During the experiment, scientists from the University of California made a material consisting of alternating layers of semiconductor dytelurized molybdenum and graphene. The thickness of the whole structure was slightly larger than the width of one DNA molecule. Further, physicists bombarded this structure with ultricular laser pulses measured by quadrillion dollars of a second.

As a result of the experiment, scientists noticed a sudden formation that they were called an abnormal ring of the photocurrent and found signs of electrons condensation and their positively charged holes in the equivalent of liquid. According to the team, the substance has properties reminiscent of the usual fluid, except that it consists not from molecules, but from individual elementary particles. However, researchers surprised that the exotic state was formed under room temperature.

Next, physicists will study the properties of exotic fluid, such as surface tension, fluidity. They also plan to use this technology to study other phenomena. For example, whether cooling is able to turn a drop into ultra-low temperatures into a «quantum liquid» with unique physical properties that will help learn new fundamental peculiarities of matter.

The team argues that due to the electronic properties of the substance, optoelectronic devices can be developed that work with high efficiency in the terahertz spectrum range. Terrahertz waves can be used to identify skin cancer, cracks in teeth, defects in products or for faster space communication systems. Liquid can also be the basis for quantum computers, allowing you to significantly reduce their dimensions, compared to those based on silicon.
