Abstract:Two-dimensional
(2D) materials have attracted attention due to
their excellent optoelectronic properties, but their applications
are limited by their defects and vacancies. Surface modification is
an effective method to restore their performance. Here, ZrSe2 is modified with conductive polymer p-toluenesulfonic
acid (PTSA). It is found that PTSA can obtain electrons of ZrSe2 through the combination of −SO3H and ZrSe2, thus forming interfacial dipoles, which improve the work
function of ZrSe2. In addition, −OH … Show more
