The ability to continuously control the bandgap in optoelectronic materials, in a low-cost manner, is highly desirable for a wide range of energy and sensing applications, including photovoltaics ...

The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...

When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...
