First claim
Opening claim text (preview).
What is claimed is: 1. A two-dimensional layer comprising M-R, wherein M is selected from the group consisting of Ge, and Sn; wherein R is C 1-18 alkyl; and wherein the M-R is crystalline. 2. The two-dimensional layer of claim 1 , wherein M is Ge. 3. The two-dimensional layer of claim 1 , wherein R is CH 3 . 4. The two-dimensional layer of claim 1 , wherein the layer is stable up to about 300° C. 5. The two-dimensional layer of claim 1 , wherein the layer has a band gap of from about 0.1 eV to about 3.4 eV. 6. A stack comprising the two-dimensional layer of claim 1 . 7. The stack of claim 6 , wherein M is Ge. 8. The stack of claim 6 , wherein R is CH 3 . 9. A two-dimensional layer of claim 1 , wherein M-R is Ge(CH 3 ). 10. A stack comprising the two-dimensional layer of claim 9 . 11. The two-dimensional layer of claim 1 , wherein R is a branched or unbranched hydrocarbon. 12. A light-emitting device comprising the two-dimensional layer of claim 1 . 13. The light-emitting device of claim 12 , wherein the light-emitting device is selected from the group consisting of light-emitting diodes and lasers. 14. The light-emitting device of claim 12 , wherein the two dimensional layer comprises GeCH 3 . 15. A light-absorbing device comprising the two dimensional layer of claim 1 . 16. The light-absorbing device of claim 15 , wherein the light-absorbing device is selected from the group consisting of photovoltaics and photodetectors. 17. The light-absorbing device of claim 15 , wherein the two dimensional layer comprises GeCH 3 . 18. A transistor comprising the two-dimensional layer of claim 1 . 19. The transistor of claim 18 , wherein the two dimensional layer comprises GeCH 3 .
