Abstract
The authors present the results obtained by wavelength and thermally modulating the reflectivity of the layer compound GaTe up to about 5 eV. The E1 and E3 structures are explained in terms of a two-dimensional M0+M1 metamorphism and an M2 two-dimensional critical point respectively. Furthermore a certain amount of information on the excitonic nature of some observed structure is presented and a clear relationship is found with the optical spectra of GaS and GaSe.Keywords
