Graphene(s): Tuning their Nonlinear Optical Response

Effect and mechanism analysis of surface hydrogenation and fluorination on the electronic properties of th-GeC2

“…28 Some research groups also have tuned the electronic properties of th-GeC 2 by applying alloying, uniaxial strain, or changing the thickness of the structure. 21,32 In addition to the above methods, surface functionalization is also a very important approach for modifying the electronic properties of many 2D materials, such as tetrahex-carbon, 33 C568, 34 graphene, [35][36][37][38] other allotropes of carbon, 39 etc. Atomic species, such as hydrogen (H), fluorine (F), chlorine (Cl), and oxygen (O) atoms, 12,[40][41][42] are generally used to modify the covalent bonds of g-GeC and result in materials possessing very unusual properties such that 2D GeC can be used in magnetic devices 12,40 or the optical response expands to the visible 41 or near-ultraviolet light 42 region.…”
