Another semiconducting material that is just three atomic layers thick has developed with more fascinating, malleable electronic properties than those of conventional semiconductors.These properties originate from electrons, similar to a ball moving down a slope to a valley, that lean toward the lower energy levels at the base of electronic energy “valleys.” Now, the valley depth can be moved optically and with compelling pace with sculpted laser pulses..

Electrons have distinct energy levels ranging from high energy levels to low levels, like a ball moving down a mountain to a valley. In the imaginatively upgraded  depiction,, a valley in the electronic structure interfaces with and is regulatory  manipulated by circularly captivated laser light. The laser causes valleys with at first equivalent energies to have marginally distinctive energies. It is the first time through a laser has split valleys in an atomically thin semiconductor (tungsten disulfide),This semiconductor could bring about in advanced electronics grounded on the energy valley rather than conventional electronics based on charge accumulation and flows.
