Bat\_xKxBiO3 is to date the highest Tc member of a class of superconductors which, it could be argued, belong in the same class of materials as the copper oxides. While there are striking differences between the bismuthates and the cuprates, there are some similarities. In this paper, we will report

Raman and intrared measurements were conducted on Bal-xKxBiO3 single crystals as a function of potassium concentration x, The sample with x=0,5 was found to superconduct below 32 K, while the other two samples with x=0.2 and 1.0 were semiconducting and insulating, respectively. The observed peaks in
Nonlinear, field-modulated, direct microwave absorption (FMMA) was observed in copper-free Ba~ ,K~BiO3 powder sampies. The high-field, low-temperature results were compared to previous measurements ofYBa CuO and BiSrCaCuO. The microwave determined critical field #oH\* = 0.7 p\_T and depinning curren
We have grown Bal \_~K.~BiO3/BaBi2Oy/Bal \_xKxBiO3 trilayers by molecular beam epitaxy. Junctions made from these trilayers exhibit transport ranging from hopping conduction to superconductor-insulator-normal metal tunneling and possibly to superconductor-insulator-superconductor Josephson tunneling
