Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other
show versatility for studying exotic quantum phenomena. In particular, anisotropic layered …

We study the breakpoint region on the outermost branch of the current-voltage
characteristics of stacks with different numbers of intrinsic Josephson junctions. We show …

Terahertz (THz) emission has been recently detected from intrinsic Josephson junction (IJJ)
stacks made of the high critical temperature superconductor Bi 2 Sr 2 CaCu 2 O 8+ δ …

We have observed the zero-crossing steps in a surface junction of a mesa structure
microfabricated on the surface of a Bi 2 Sr 2 CaCu 2 O 8+ δ single crystal. With the …

By feeding current into the topmost Cu 2 O 4 layer of a mesa etched into the surface of a Bi 2
Sr 2 Ca Cu 2 O 8+ x (BSCCO) single crystal, we measured its superconducting critical value …

The microwave response of small stacks of intrinsic Josephson junctions in HgI 2−
intercalated Bi 2 Sr 2 CaCu 2 O 8+ δ single crystals was studied. When irradiated with a …

More sensitive (especially due to reduced interference of flux noise) than a conventional
SQUID, an inventive SQUID's major component is a hollow cylindric structure comprising …

Transport properties of small-sized intrinsic Josephson junctions in Bi2Sr2CaCu2Oy have
been systematically investigated with respect to both junction size and temperature. Using …

We report on the first observation of clear voltage modulation in dc SQUID based on intrinsic
Josephson junctions of Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub y/. Stacked series array of …

The operational direct-current superconducting quantum interference device (dc-SQUID)
based on intrinsic Josephson junctions in Bi 2 Sr 2 CaCu 2 O 8+ δ high-T c superconductor …
