Consider the two-dimensional lattice $G=(\mathbb{Z}^2,\mathbb{E}^2)$, where edge set $\mathbb{E}^2$ is given by the pairs of nearest neighbors in the $\ell^1$ norm in $\mathbb{Z}^2$. Let $V\subset\mathbb{Z}^2$ an infinite subset and suppose that $G[V]$, the induced subgraph, is connected. Let $\Lambda_n=([-n,n]\times[-n,n])\cap \mathbb{Z}^2$ be a sequence of squares on the two-dimensional lattice. Suppose additionally that $$ \limsup_{n\to\infty} \frac{|V\cap \Lambda_n|}{|\Lambda_n|}=0. $$ Question: under the above conditions is it true that the independent bond percolation, with parameter $p$, on $G[V]$ is trivial, in the sense that for any $p\in [0,1)$ we do not have almost surely an infinite cluster ?
I suspect that the answer is affirmative and this is considered in the literature, but until now I only found trivial examples of such graphs $G[V]$, basically constructed from the one-dimensional lattice, where there is no percolation.
