N2 - Two different types of Cooper pair transistors, with Al and Nb islands, have been investigated in atunable electromagnetic environment. The device with an Al island demonstrates gate chargemodulation with 2e periodicity in a wide range of environmental impedances at bath temperaturesbelow 340 mK. Contrary to the results of the Al sample, the authors were not able to detect 2eperiodicity under any conditions on similar samples with Nb island. The authors attribute this to thematerial properties of Nb.
